Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Pasha is participating in a contest on one well-known website. This time he wants to win the contest and will do anything to get to the first place!
This contest consists of n problems, and Pasha solves ith problem in ai time units (his solutions are always correct). At any moment of time he can be thinking about a solution to only one of the problems (that is, he cannot be solving two problems at the same time). The time Pasha spends to send his solutions is negligible. Pasha can send any number of solutions at the same moment.
Unfortunately, there are too many participants, and the website is not always working. Pasha received the information that the website will be working only during m time periods, jth period is represented by its starting moment lj and ending moment rj. Of course, Pasha can send his solution only when the website is working. In other words, Pasha can send his solution at some moment T iff there exists a period x such that lx ≤ T ≤ rx.
Pasha wants to know his best possible result. We need to tell him the minimal moment of time by which he is able to have solutions to all problems submitted, if he acts optimally, or say that it's impossible no matter how Pasha solves the problems.
Input
The first line contains one integer n (1 ≤ n ≤ 1000) — the number of problems. The second line contains n integers ai (1 ≤ ai ≤ 105) — the time Pasha needs to solve ith problem.
The third line contains one integer m (0 ≤ m ≤ 1000) — the number of periods of time when the website is working. Next m lines represent these periods. jth line contains two numbers lj and rj (1 ≤ lj < rj ≤ 105) — the starting and the ending moment of jth period.
It is guaranteed that the periods are not intersecting and are given in chronological order, so for every j > 1 the condition lj > rj - 1 is met.
Output
If Pasha can solve and submit all the problems before the end of the contest, print the minimal moment of time by which he can have all the solutions submitted.
Otherwise print "-1" (without brackets).

Note
In the first example Pasha can act like this: he solves the second problem in 4 units of time and sends it immediately. Then he spends 3 time units to solve the first problem and sends it 7 time units after the contest starts, because at this moment the website starts working again.
In the second example Pasha invents the solution only after the website stops working for the last time.
In the third example Pasha sends the solution exactly at the end of the first period.

problem
You are in charge of quality control at a machine manufacturing plant. This machine requires a power supply, a motor, and a cable as parts. The manufacturing plant has a power supply, b motors, and c cables, numbered from 1 to a, a + 1 to a + b, and a + b + 1 to a + b + c, respectively. attached. The trouble is that some parts may be out of order. I want to know which parts are out of order and which parts are normal in the factory.
Therefore, the factory inspected the parts by the following method. Bring the power supply, motor, and cable one by one, connect them, and try to operate them. At this time, if all three parts are normal, it operates correctly and is recognized as "passed". If any of the three parts is out of order, it will not operate properly and will be recognized as "failed". (Since the machines made in the factory are so precise, it does not happen that the broken parts are mixed and operate correctly by accident.)
You will be given a list of test results. Each line in the list of test results shows the numbers of the power supply, motor, and cable used for the test, and whether the test passed or failed.
Given a list of inspection results, all parts are either faulty or normal from the inspection results, some are definitely faulty, some are definitely normal. Create a program to classify parts that are not decided.
input
The input consists of multiple datasets. The format of each data set is as follows. The input ends on a line containing three zeros.
Three integers are written on the first line, separated by blanks, and represent the number of power supplies a, the number of motors b, and the number of cables c in order.
One integer is written on the second line, and the number of tests N included in the list of test results is written.
The next N lines represent a list of test results. On each line, four integers i, j, k, r are written with one blank as a delimiter, and the result of inspection by connecting the power supply i, the motor j, and the cable k is "pass" (r = 1). (When) or "Fail" (when r = 0).
a, b, c, N satisfy 1 ≤ a, b, c ≤ 100, 1 ≤ N ≤ 1000.
The number of datasets does not exceed 5.
output
Output in the following format for each data set. The output of each dataset consists of lines a + b + c.
Line i (1 ≤ i ≤ a + b + c):
* If the inspection result shows that the part i is out of order, 0 is output.
* If the inspection result shows that the part i is normal, 1 is output.
* Output 2 if the inspection result does not determine whether part i is defective or normal.

The manufacturing plant has a power supply, b motors, and c cables, numbered from 1 to a, a + 1 to a + b, and a + b + 1 to a + b + c, respectively. attached. The trouble is that some parts may be out of order. I want to know which parts are out of order and which parts are normal in the factory.
Therefore, the factory inspected the parts by the following method. Bring the power supply, motor, and cable one by one, connect them, and try to operate them. At this time, if all three parts are normal, it operates correctly and is recognized as "passed". If any of the three parts is out of order, it will not operate properly and will be recognized as "failed". (Since the machines made in the factory are so precise, it does not happen that the broken parts are mixed and operate correctly by accident.)
You will be given a list of test results. Each line in the list of test results shows the numbers of the power supply, motor, and cable used for the test, and whether the test passed or failed.
Given a list of inspection results, all parts are either faulty or normal from the inspection results, some are definitely faulty, some are definitely normal. Create a program to classify parts that are not decided.
input
The input consists of multiple datasets. The format of each data set is as follows. The input ends on a line containing three zeros.
Three integers are written on the first line, separated by blanks, and represent the number of power supplies a, the number of motors b, and the number of cables c in order.
One integer is written on the second line, and the number of tests N included in the list of test results is written.
The next N lines represent a list of test results. On each line, four integers i, j, k, r are written with one blank as a delimiter, and the result of inspection by connecting the power supply i, the motor j, and the cable k is "pass" (r = 1). (When) or "Fail" (when r = 0).
a, b, c, N satisfy 1 ≤ a, b, c ≤ 100, 1 ≤ N ≤ 1000.
The number of datasets does not exceed 5.
output
Output in the following format for each data set. The output of each dataset consists of lines a + b + c.
Line i (1 ≤ i ≤ a + b + c):
* If the inspection result shows that the part i is out of order, 0 is output.
* If the inspection result shows that the part i is normal, 1 is output.
* Output 2 if the inspection result does not determine whether part i is defective or normal.

Provide a correct Python 3 solution for this coding contest problem.
JAG mock qualifying practice session
The ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG) has N questions in stock of questions to be asked in the mock contest, and each question is numbered with an integer from 1 to N. Difficulty evaluation and recommendation voting are conducted for each problem. Problem i has a difficulty level of di and a recommendation level of vi. The maximum difficulty level is M.
In the next contest, we plan to ask a total of M questions, one for each of the difficulty levels 1 to M. In order to improve the quality of the contest, I would like to select the questions so that the total recommendation level is maximized. However, since JAG's questioning ability is tremendous, it can be assumed that there is at least one question for each difficulty level.
Your job is to create a program that finds the maximum sum of the sums of recommendations when the questions are selected to meet the conditions.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> N M
> d1 v1
> ...
> dN vN
>
The first line of the dataset is given an integer N, which represents the number of problem stocks, and a maximum difficulty value, M, separated by blanks. These numbers satisfy 1 ≤ M ≤ N ≤ 100. On the i-th line of the following N lines, the integers di and vi representing the difficulty level and recommendation level of problem i are given, separated by blanks. These numbers satisfy 1 ≤ di ≤ M and 0 ≤ vi ≤ 100. Also, for each 1 ≤ j ≤ M, it is guaranteed that there is at least one i such that di = j.
> The end of the input is represented by two zeros separated by a blank. Also, the number of datasets does not exceed 50.
> ### Output
For each data set, output the maximum value of the sum of the recommendation levels of the questions to be asked when one question is asked from each difficulty level on one line.

JAG mock qualifying practice session
The ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG) has N questions in stock of questions to be asked in the mock contest, and each question is numbered with an integer from 1 to N. Difficulty evaluation and recommendation voting are conducted for each problem. Problem i has a difficulty level of di and a recommendation level of vi. The maximum difficulty level is M.
In the next contest, we plan to ask a total of M questions, one for each of the difficulty levels 1 to M. In order to improve the quality of the contest, I would like to select the questions so that the total recommendation level is maximized. However, since JAG's questioning ability is tremendous, it can be assumed that there is at least one question for each difficulty level.
Your job is to create a program that finds the maximum sum of the sums of recommendations when the questions are selected to meet the conditions.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> N M
> d1 v1
> ...
> dN vN
>
The first line of the dataset is given an integer N, which represents the number of problem stocks, and a maximum difficulty value, M, separated by blanks. These numbers satisfy 1 ≤ M ≤ N ≤ 100. On the i-th line of the following N lines, the integers di and vi representing the difficulty level and recommendation level of problem i are given, separated by blanks. These numbers satisfy 1 ≤ di ≤ M and 0 ≤ vi ≤ 100. Also, for each 1 ≤ j ≤ M, it is guaranteed that there is at least one i such that di = j.
> The end of the input is represented by two zeros separated by a blank. Also, the number of datasets does not exceed 50.
> ### Output
For each data set, output the maximum value of the sum of the recommendation levels of the questions to be asked when one question is asked from each difficulty level on one line.

JAG mock qualifying practice session
The ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG) has N questions in stock of questions to be asked in the mock contest, and each question is numbered with an integer from 1 to N. Difficulty evaluation and recommendation voting are conducted for each problem. Problem i has a difficulty level of di and a recommendation level of vi. The maximum difficulty level is M.
In the next contest, we plan to ask a total of M questions, one for each of the difficulty levels 1 to M. In order to improve the quality of the contest, I would like to select the questions so that the total recommendation level is maximized. However, since JAG's questioning ability is tremendous, it can be assumed that there is at least one question for each difficulty level.
Your job is to create a program that finds the maximum sum of the sums of recommendations when the questions are selected to meet the conditions.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> N M
> d1 v1
> ...
> dN vN
>
The first line of the dataset is given an integer N, which represents the number of problem stocks, and a maximum difficulty value, M, separated by blanks. These numbers satisfy 1 ≤ M ≤ N ≤ 100. On the i-th line of the following N lines, the integers di and vi representing the difficulty level and recommendation level of problem i are given, separated by blanks. These numbers satisfy 1 ≤ di ≤ M and 0 ≤ vi ≤ 100. Also, for each 1 ≤ j ≤ M, it is guaranteed that there is at least one i such that di = j.
> The end of the input is represented by two zeros separated by a blank. Also, the number of datasets does not exceed 50.
> ### Output
For each data set, output the maximum value of the sum of the recommendation levels of the questions to be asked when one question is asked from each difficulty level on one line.

The ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG) has N questions in stock of questions to be asked in the mock contest, and each question is numbered with an integer from 1 to N. Difficulty evaluation and recommendation voting are conducted for each problem. Problem i has a difficulty level of di and a recommendation level of vi. The maximum difficulty level is M.
In the next contest, we plan to ask a total of M questions, one for each of the difficulty levels 1 to M. In order to improve the quality of the contest, I would like to select the questions so that the total recommendation level is maximized. However, since JAG's questioning ability is tremendous, it can be assumed that there is at least one question for each difficulty level.
Your job is to create a program that finds the maximum sum of the sums of recommendations when the questions are selected to meet the conditions.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> N M
> d1 v1
> ...
> dN vN
>
The first line of the dataset is given an integer N, which represents the number of problem stocks, and a maximum difficulty value, M, separated by blanks. These numbers satisfy 1 ≤ M ≤ N ≤ 100. On the i-th line of the following N lines, the integers di and vi representing the difficulty level and recommendation level of problem i are given, separated by blanks. These numbers satisfy 1 ≤ di ≤ M and 0 ≤ vi ≤ 100. Also, for each 1 ≤ j ≤ M, it is guaranteed that there is at least one i such that di = j.
> The end of the input is represented by two zeros separated by a blank. Also, the number of datasets does not exceed 50.
> ### Output
For each data set, output the maximum value of the sum of the recommendation levels of the questions to be asked when one question is asked from each difficulty level on one line.

Provide tags and a correct Python 3 solution for this coding contest problem.
This is an interactive problem. Remember to flush your output while communicating with the testing program. You may use fflush(stdout) in C++, system.out.flush() in Java, stdout.flush() in Python or flush(output) in Pascal to flush the output. If you use some other programming language, consult its documentation. You may also refer to the guide on interactive problems: <https://codeforces.com/blog/entry/45307>.
The jury guessed some array a consisting of 6 integers. There are 6 special numbers — 4, 8, 15, 16, 23, 42 — and each of these numbers occurs in a exactly once (so, a is some permutation of these numbers).
You don't know anything about their order, but you are allowed to ask up to 4 queries. In each query, you may choose two indices i and j (1 ≤ i, j ≤ 6, i and j are not necessarily distinct), and you will get the value of a_i ⋅ a_j in return.
Can you guess the array a?
The array a is fixed beforehand in each test, the interaction program doesn't try to adapt to your queries.
Interaction
Before submitting the answer, you may ask up to 4 queries. To ask a query, print one line in the following format: ? i j, where i and j should be two integers such that 1 ≤ i, j ≤ 6. The line should be ended with a line break character. After submitting a query, flush the output and read the answer to your query — one line containing one integer a_i ⋅ a_j. If you submit an incorrect query (or ask more than 4 queries), the answer to it will be one string 0. After receiving such an answer, your program should terminate immediately — otherwise you may receive verdict "Runtime error", "Time limit exceeded" or some other verdict instead of "Wrong answer".
To give the answer, your program should print one line ! a_1 a_2 a_3 a_4 a_5 a_6 with a line break in the end. After that, it should flush the output and terminate gracefully.

345
672
Output
? 1 1
? 2 2
? 3 5
? 4 6

Note
If you want to submit a hack for this problem, your test should contain exactly six space-separated integers a_1, a_2, ..., a_6. Each of 6 special numbers should occur exactly once in the test. The test should be ended with a line break character. | instruction | 0 | 53,118 | 11 | 106,236 |

The line should be ended with a line break character. After submitting a query, flush the output and read the answer to your query — one line containing one integer a_i ⋅ a_j. If you submit an incorrect query (or ask more than 4 queries), the answer to it will be one string 0. After receiving such an answer, your program should terminate immediately — otherwise you may receive verdict "Runtime error", "Time limit exceeded" or some other verdict instead of "Wrong answer".
To give the answer, your program should print one line ! a_1 a_2 a_3 a_4 a_5 a_6 with a line break in the end. After that, it should flush the output and terminate gracefully.

Note
If you want to submit a hack for this problem, your test should contain exactly six space-separated integers a_1, a_2, ..., a_6. Each of 6 special numbers should occur exactly once in the test. The test should be ended with a line break character.

This is an interactive problem. Remember to flush your output while communicating with the testing program. You may use fflush(stdout) in C++, system.out.flush() in Java, stdout.flush() in Python or flush(output) in Pascal to flush the output. If you use some other programming language, consult its documentation. You may also refer to the guide on interactive problems: <https://codeforces.com/blog/entry/45307>.
The jury guessed some array a consisting of 6 integers. There are 6 special numbers — 4, 8, 15, 16, 23, 42 — and each of these numbers occurs in a exactly once (so, a is some permutation of these numbers).
You don't know anything about their order, but you are allowed to ask up to 4 queries. In each query, you may choose two indices i and j (1 ≤ i, j ≤ 6, i and j are not necessarily distinct), and you will get the value of a_i ⋅ a_j in return.
Can you guess the array a?
The array a is fixed beforehand in each test, the interaction program doesn't try to adapt to your queries.

Jou and Yae are a good couple. Jou is collecting prizes for capsule toy vending machines (Gachapon), and even when they go out together, when they find Gachapon, they seem to get so hot that they try it several times. Yae was just looking at Jou, who looked happy, but decided to give him a Gachapon prize for his upcoming birthday present. Yae wasn't very interested in Gachapon itself, but hopefully he would like a match with Jou.
For Gachapon that Yae wants to try, one prize will be given in one challenge. You can see how many types of prizes there are, including those that are out of stock, and how many of each prize remains. However, I don't know which prize will be given in one challenge. Therefore, regardless of the order in which the prizes are given, create a program that outputs the minimum number of challenges required for Yae to get two of the same prizes.
input
The input consists of multiple datasets. The end of the input is indicated by a single line of zeros. Each dataset is given in the following format:
N
k1 k2 ... kN
Each dataset has two lines, and the first line is given the integer N (1 ≤ N ≤ 10000), which indicates how many types of prizes there are. The next line is given the integer ki (0 ≤ ki ≤ 10000), which indicates how many prizes are left.
The number of datasets does not exceed 100.
output
For each dataset, the minimum number of challenges required to get two identical prizes is output. However, if it is not possible, NA is output.

Problem
There are N villages. Each village is numbered from 1 to N. Due to the recent merger boom, several villages have been merged. Two or more merged villages will become one new city, and villages that are not merged with any village will remain villages.
You will be given multiple pieces of information that two villages will be in the same city after the merger. Depending on the combination of the information, three or more villages can become one city.
Given information about villages that will be in the same city after the merger, output the absolute value of the difference between the number of cities and the number of villages after the merger.
Constraints
* 1 ≤ N ≤ 1,000
* 0 ≤ M ≤ 100
* 1 ≤ ai ≤ N
* 1 ≤ bi ≤ N
Input
The input is given in the following format.
N M
a1 b1
a2 b2
...
ai bi
...
aM bM
The first line gives the number N of villages and the number M of information about the merger, separated by blanks.
From the second line to the M + 1 line, two integers ai and bi representing information about the merger are given, separated by blanks. Each information indicates that the ai and bi villages will be the same city after the merger. However, no input is given that satisfies ai = bi.
Output
Output the absolute value of the difference between the number of villages and the number of cities on one line.

You are given a rebus of form ? + ? - ? + ? = n, consisting of only question marks, separated by arithmetic operation '+' and '-', equality and positive integer n. The goal is to replace each question mark with some positive integer from 1 to n, such that equality holds.
Input
The only line of the input contains a rebus. It's guaranteed that it contains no more than 100 question marks, integer n is positive and doesn't exceed 1 000 000, all letters and integers are separated by spaces, arithmetic operations are located only between question marks.
Output
The first line of the output should contain "Possible" (without quotes) if rebus has a solution and "Impossible" (without quotes) otherwise.
If the answer exists, the second line should contain any valid rebus with question marks replaced by integers from 1 to n. Follow the format given in the samples.

You are given a rebus of form ? + ? - ? + ? = n, consisting of only question marks, separated by arithmetic operation '+' and '-', equality and positive integer n. The goal is to replace each question mark with some positive integer from 1 to n, such that equality holds.
Input
The only line of the input contains a rebus. It's guaranteed that it contains no more than 100 question marks, integer n is positive and doesn't exceed 1 000 000, all letters and integers are separated by spaces, arithmetic operations are located only between question marks.
Output
The first line of the output should contain "Possible" (without quotes) if rebus has a solution and "Impossible" (without quotes) otherwise.
If the answer exists, the second line should contain any valid rebus with question marks replaced by integers from 1 to n. Follow the format given in the samples.
Examples
Input
? + ? - ? + ? + ? = 42
Output
Possible
9 + 13 - 39 + 28 + 31 = 42
Input
? - ? = 1
Output

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
You will be given a contest schedule for D days. For each d=1,2,\ldots,D, calculate the satisfaction at the end of day d.
Input
Input is given from Standard Input in the form of the input of Problem A followed by the output of Problem A.
D
c_1 c_2 \cdots c_{26}
s_{1,1} s_{1,2} \cdots s_{1,26}
\vdots
s_{D,1} s_{D,2} \cdots s_{D,26}
t_1
t_2
\vdots
t_D
* The constraints and generation methods for the input part are the same as those for Problem A.
* For each d, t_d is an integer satisfying 1\leq t_d \leq 26, and your program is expected to work correctly for any value that meets the constraints.
Output
Let v_d be the satisfaction at the end of day d. Print D integers v_d to Standard Output in the following format:
v_1
v_2
\vdots
v_D
Output
Let v_d be the satisfaction at the end of day d. Print D integers v_d to Standard Output in the following format:
v_1
v_2
\vdots
