Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A team of three programmers is going to play a contest. The contest consists of n problems, numbered from 1 to n. Each problem is printed on a separate sheet of paper. The participants have decided to divide the problem statements into three parts: the first programmer took some prefix of the statements (some number of first paper sheets), the third contestant took some suffix of the statements (some number of last paper sheets), and the second contestant took all remaining problems. But something went wrong — the statements were printed in the wrong order, so the contestants have received the problems in some random order.
The first contestant has received problems a_{1, 1}, a_{1, 2}, ..., a_{1, k_1}. The second one has received problems a_{2, 1}, a_{2, 2}, ..., a_{2, k_2}. The third one has received all remaining problems (a_{3, 1}, a_{3, 2}, ..., a_{3, k_3}).
The contestants don't want to play the contest before they redistribute the statements. They want to redistribute them so that the first contestant receives some prefix of the problemset, the third contestant receives some suffix of the problemset, and the second contestant receives all the remaining problems.
During one move, some contestant may give one of their problems to other contestant. What is the minimum number of moves required to redistribute the problems?
It is possible that after redistribution some participant (or even two of them) will not have any problems.
Input
The first line contains three integers k_1, k_2 and k_3 (1 ≤ k_1, k_2, k_3 ≤ 2 ⋅ 10^5, k_1 + k_2 + k_3 ≤ 2 ⋅ 10^5) — the number of problems initially taken by the first, the second and the third participant, respectively.
The second line contains k_1 integers a_{1, 1}, a_{1, 2}, ..., a_{1, k_1} — the problems initially taken by the first participant.
The third line contains k_2 integers a_{2, 1}, a_{2, 2}, ..., a_{2, k_2} — the problems initially taken by the second participant.
The fourth line contains k_3 integers a_{3, 1}, a_{3, 2}, ..., a_{3, k_3} — the problems initially taken by the third participant.
It is guaranteed that no problem has been taken by two (or three) participants, and each integer a_{i, j} meets the condition 1 ≤ a_{i, j} ≤ n, where n = k_1 + k_2 + k_3.
Output
Print one integer — the minimum number of moves required to redistribute the problems so that the first participant gets the prefix of the problemset, the third participant gets the suffix of the problemset, and the second participant gets all of the remaining problems.

Note
In the first example the third contestant should give the problem 2 to the first contestant, so the first contestant has 3 first problems, the third contestant has 1 last problem, and the second contestant has 1 remaining problem.
In the second example the distribution of problems is already valid: the first contestant has 3 first problems, the third contestant has 1 last problem, and the second contestant has 2 remaining problems.
The best course of action in the third example is to give all problems to the third contestant.
The best course of action in the fourth example is to give all problems to the second contestant.

Provide a correct Python 3 solution for this coding contest problem.
Joisino is about to compete in the final round of a certain programming competition. In this contest, there are N problems, numbered 1 through N. Joisino knows that it takes her T_i seconds to solve problem i(1≦i≦N).
Also, there are M kinds of drinks offered to the contestants, numbered 1 through M. If Joisino takes drink i(1≦i≦M), her brain will be stimulated and the time it takes for her to solve problem P_i will become X_i seconds. It does not affect the time to solve the other problems.
A contestant is allowed to take exactly one of the drinks before the start of the contest. For each drink, Joisino wants to know how many seconds it takes her to solve all the problems if she takes that drink. Here, assume that the time it takes her to solve all the problems is equal to the sum of the time it takes for her to solve individual problems. Your task is to write a program to calculate it instead of her.
Constraints
* All input values are integers.
* 1≦N≦100
* 1≦T_i≦10^5
* 1≦M≦100
* 1≦P_i≦N
* 1≦X_i≦10^5
Input
The input is given from Standard Input in the following format:
N
T_1 T_2 ... T_N
M
P_1 X_1
P_2 X_2
:
P_M X_M
Output
For each drink, calculate how many seconds it takes Joisino to solve all the problems if she takes that drink, and print the results, one per line.

Provide a correct Python 3 solution for this coding contest problem.
Joisino is about to compete in the final round of a certain programming competition. In this contest, there are N problems, numbered 1 through N. Joisino knows that it takes her T_i seconds to solve problem i(1≦i≦N).
Also, there are M kinds of drinks offered to the contestants, numbered 1 through M. If Joisino takes drink i(1≦i≦M), her brain will be stimulated and the time it takes for her to solve problem P_i will become X_i seconds. It does not affect the time to solve the other problems.
A contestant is allowed to take exactly one of the drinks before the start of the contest. For each drink, Joisino wants to know how many seconds it takes her to solve all the problems if she takes that drink. Here, assume that the time it takes her to solve all the problems is equal to the sum of the time it takes for her to solve individual problems. Your task is to write a program to calculate it instead of her.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Joisino is about to compete in the final round of a certain programming competition. In this contest, there are N problems, numbered 1 through N. Joisino knows that it takes her T_i seconds to solve problem i(1≦i≦N).
Also, there are M kinds of drinks offered to the contestants, numbered 1 through M. If Joisino takes drink i(1≦i≦M), her brain will be stimulated and the time it takes for her to solve problem P_i will become X_i seconds. It does not affect the time to solve the other problems.
A contestant is allowed to take exactly one of the drinks before the start of the contest. For each drink, Joisino wants to know how many seconds it takes her to solve all the problems if she takes that drink. Here, assume that the time it takes her to solve all the problems is equal to the sum of the time it takes for her to solve individual problems. Your task is to write a program to calculate it instead of her.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sasha grew up and went to first grade. To celebrate this event her mother bought her a multiplication table M with n rows and n columns such that M_{ij}=a_i ⋅ a_j where a_1, ..., a_n is some sequence of positive integers.
Of course, the girl decided to take it to school with her. But while she was having lunch, hooligan Grisha erased numbers on the main diagonal and threw away the array a_1, ..., a_n. Help Sasha restore the array!
Input
The first line contains a single integer n (3 ⩽ n ⩽ 10^3), the size of the table.
The next n lines contain n integers each. The j-th number of the i-th line contains the number M_{ij} (1 ≤ M_{ij} ≤ 10^9). The table has zeroes on the main diagonal, that is, M_{ii}=0.
Output
In a single line print n integers, the original array a_1, ..., a_n (1 ≤ a_i ≤ 10^9). It is guaranteed that an answer exists. If there are multiple answers, print any.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
You are given a sequence of positive integers a1, a2, ..., an. Find all such indices i, that the i-th element equals the arithmetic mean of all other elements (that is all elements except for this one).
Input
The first line contains the integer n (2 ≤ n ≤ 2·105). The second line contains elements of the sequence a1, a2, ..., an (1 ≤ ai ≤ 1000). All the elements are positive integers.
Output
Print on the first line the number of the sought indices. Print on the second line the sought indices in the increasing order. All indices are integers from 1 to n.
If the sought elements do not exist, then the first output line should contain number 0. In this case you may either not print the second line or print an empty line.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A team quiz game called "What? Where? When?" is very popular in Berland. The game is centered on two teams competing. They are the team of six Experts versus the team of the Audience. A person from the audience asks a question and the experts are allowed a minute on brainstorming and finding the right answer to the question. All it takes to answer a typical question is general knowledge and common logic. The question sent be the audience are in envelops lain out in a circle on a round table. Each envelop is marked by the name of the asker's town. Each question is positioned in a separate sector. In the centre of the table is a spinning arrow. Thus, the table rather resembles a roulette table with no ball but with a spinning arrow instead. The host sets off the spinning arrow to choose a question for the experts: when the arrow stops spinning, the question it is pointing at is chosen. If the arrow points at the question that has already been asked, the host chooses the next unanswered question in the clockwise direction. Your task is to determine which will be the number of the next asked question if the arrow points at sector number k.
Input
The first line contains two positive integers n and k (1 ≤ n ≤ 1000 and 1 ≤ k ≤ n) — the numbers of sectors on the table and the number of the sector where the arrow is pointing. The second line contains n numbers: ai = 0 if the question from sector i has already been asked and ai = 1 if the question from sector i hasn't been asked yet (1 ≤ i ≤ n). The sectors are given in the clockwise order, the first sector follows after the n-th one.
Output
Print the single number — the number of the sector containing the question the experts will be asked. It is guaranteed that the answer exists, that is that not all the questions have already been asked.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Almost Identical Programs
The programming contest named Concours de Programmation Comtemporaine Interuniversitaire (CPCI) has a judging system similar to that of ICPC; contestants have to submit correct outputs for two different inputs to be accepted as a correct solution. Each of the submissions should include the program that generated the output. A pair of submissions is judged to be a correct solution when, in addition to the correctness of the outputs, they include an identical program.
Many contestants, however, do not stop including a different version of their programs in their second submissions, after modifying a single string literal in their programs representing the input file name, attempting to process different input. The organizers of CPCI are exploring the possibility of showing a special error message for such close submissions, indicating contestants what's wrong with such submissions. Your task is to detect such close submissions.
Input
The input consists of at most 100 datasets, each in the following format.
s1
s2
Each of s1 and s2 is a string written in a line, with the length between 1 and 200, inclusive. They are the first and the second submitted programs respectively. A program consists of lowercase letters (`a`, `b`, ..., `z`), uppercase letters (`A`, `B`, ..., `Z`), digits (`0`, `1`, ..., `9`), double quotes (`"`), and semicolons (`;`). When double quotes occur in a program, there are always even number of them.
The end of the input is indicated by a line containing one '`.`' (period).
Output
For each dataset, print the judge result in a line.
If the given two programs are identical, print `IDENTICAL`. If two programs differ with only one corresponding string literal, print `CLOSE`. Otherwise, print `DIFFERENT`. A string literal is a possibly empty sequence of characters between an odd-numbered occurrence of a double quote and the next occurrence of a double quote.

The end of the input is indicated by a line containing one '`.`' (period).
Output
For each dataset, print the judge result in a line.
If the given two programs are identical, print `IDENTICAL`. If two programs differ with only one corresponding string literal, print `CLOSE`. Otherwise, print `DIFFERENT`. A string literal is a possibly empty sequence of characters between an odd-numbered occurrence of a double quote and the next occurrence of a double quote.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Almost Identical Programs
The programming contest named Concours de Programmation Comtemporaine Interuniversitaire (CPCI) has a judging system similar to that of ICPC; contestants have to submit correct outputs for two different inputs to be accepted as a correct solution. Each of the submissions should include the program that generated the output. A pair of submissions is judged to be a correct solution when, in addition to the correctness of the outputs, they include an identical program.
Many contestants, however, do not stop including a different version of their programs in their second submissions, after modifying a single string literal in their programs representing the input file name, attempting to process different input. The organizers of CPCI are exploring the possibility of showing a special error message for such close submissions, indicating contestants what's wrong with such submissions. Your task is to detect such close submissions.
Input
The input consists of at most 100 datasets, each in the following format.
s1
s2
Each of s1 and s2 is a string written in a line, with the length between 1 and 200, inclusive. They are the first and the second submitted programs respectively. A program consists of lowercase letters (`a`, `b`, ..., `z`), uppercase letters (`A`, `B`, ..., `Z`), digits (`0`, `1`, ..., `9`), double quotes (`"`), and semicolons (`;`). When double quotes occur in a program, there are always even number of them.
The end of the input is indicated by a line containing one '`.`' (period).
Output
For each dataset, print the judge result in a line.
If the given two programs are identical, print `IDENTICAL`. If two programs differ with only one corresponding string literal, print `CLOSE`. Otherwise, print `DIFFERENT`. A string literal is a possibly empty sequence of characters between an odd-numbered occurrence of a double quote and the next occurrence of a double quote.

Provide tags and a correct Python 3 solution for this coding contest problem.
One day a highly important task was commissioned to Vasya — writing a program in a night. The program consists of n lines of code. Vasya is already exhausted, so he works like that: first he writes v lines of code, drinks a cup of tea, then he writes as much as <image> lines, drinks another cup of tea, then he writes <image> lines and so on: <image>, <image>, <image>, ...
The expression <image> is regarded as the integral part from dividing number a by number b.
The moment the current value <image> equals 0, Vasya immediately falls asleep and he wakes up only in the morning, when the program should already be finished.
Vasya is wondering, what minimum allowable value v can take to let him write not less than n lines of code before he falls asleep.
Input
The input consists of two integers n and k, separated by spaces — the size of the program in lines and the productivity reduction coefficient, 1 ≤ n ≤ 109, 2 ≤ k ≤ 10.
Output
Print the only integer — the minimum value of v that lets Vasya write the program in one night.
Examples
Input
7 2
Output
4
Input
59 9
Output
54
Note
In the first sample the answer is v = 4. Vasya writes the code in the following portions: first 4 lines, then 2, then 1, and then Vasya falls asleep. Thus, he manages to write 4 + 2 + 1 = 7 lines in a night and complete the task.
In the second sample the answer is v = 54. Vasya writes the code in the following portions: 54, 6. The total sum is 54 + 6 = 60, that's even more than n = 59.
Tags: binary search, implementation
Correct Solution:
```
def sum_series (v, k):
power = 0
res = 0
while v // (k ** power) > 1.0e-6:
res += v // (k ** power)
power += 1
return res
n, k = list(map(int, input().split()))
low = 1
high = n
while low <= high:
v = (low + high) // 2
if sum_series(v, k) >= n:
high = v - 1
else:
low = v + 1
print(low)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
One day a highly important task was commissioned to Vasya — writing a program in a night. The program consists of n lines of code. Vasya is already exhausted, so he works like that: first he writes v lines of code, drinks a cup of tea, then he writes as much as <image> lines, drinks another cup of tea, then he writes <image> lines and so on: <image>, <image>, <image>, ...
The expression <image> is regarded as the integral part from dividing number a by number b.
The moment the current value <image> equals 0, Vasya immediately falls asleep and he wakes up only in the morning, when the program should already be finished.
Vasya is wondering, what minimum allowable value v can take to let him write not less than n lines of code before he falls asleep.
Input
The input consists of two integers n and k, separated by spaces — the size of the program in lines and the productivity reduction coefficient, 1 ≤ n ≤ 109, 2 ≤ k ≤ 10.
Output
Print the only integer — the minimum value of v that lets Vasya write the program in one night.
Examples
Input
7 2
Output
4
Input
59 9
Output
54
Note
In the first sample the answer is v = 4. Vasya writes the code in the following portions: first 4 lines, then 2, then 1, and then Vasya falls asleep. Thus, he manages to write 4 + 2 + 1 = 7 lines in a night and complete the task.
In the second sample the answer is v = 54. Vasya writes the code in the following portions: 54, 6. The total sum is 54 + 6 = 60, that's even more than n = 59.

Provide a correct Python 3 solution for this coding contest problem.
The Smart Beaver from ABBYY came up with another splendid problem for the ABBYY Cup participants! This time the Beaver invites the contest participants to check out a problem on sorting documents by their subjects. Let's describe the problem:
You've got some training set of documents. For each document you know its subject. The subject in this problem is an integer from 1 to 3. Each of these numbers has a physical meaning. For instance, all documents with subject 3 are about trade.
You can download the training set of documents at the following link: http://download4.abbyy.com/a2/X2RZ2ZWXBG5VYWAL61H76ZQM/train.zip. The archive contains three directories with names "1", "2", "3". Directory named "1" contains documents on the 1-st subject, directory "2" contains documents on the 2-nd subject, and directory "3" contains documents on the 3-rd subject. Each document corresponds to exactly one file from some directory.
All documents have the following format: the first line contains the document identifier, the second line contains the name of the document, all subsequent lines contain the text of the document. The document identifier is used to make installing the problem more convenient and has no useful information for the participants.
You need to write a program that should indicate the subject for a given document. It is guaranteed that all documents given as input to your program correspond to one of the three subjects of the training set.
Input
The first line contains integer id (0 ≤ id ≤ 106) — the document identifier. The second line contains the name of the document. The third and the subsequent lines contain the text of the document. It is guaranteed that the size of any given document will not exceed 10 kilobytes.
The tests for this problem are divided into 10 groups. Documents of groups 1 and 2 are taken from the training set, but their identifiers will not match the identifiers specified in the training set. Groups from the 3-rd to the 10-th are roughly sorted by the author in ascending order of difficulty (these groups contain documents which aren't present in the training set).
Output
Print an integer from 1 to 3, inclusive — the number of the subject the given document corresponds to.
Examples
"Correct Solution:

print('2')

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
One cold winter evening Alice and her older brother Bob was sitting at home near the fireplace and giving each other interesting problems to solve. When it was Alice's turn, she told the number n to Bob and said:
—Shuffle the digits in this number in order to obtain the smallest possible number without leading zeroes.
—No problem! — said Bob and immediately gave her an answer.
Alice said a random number, so she doesn't know whether Bob's answer is correct. Help her to find this out, because impatient brother is waiting for the verdict.
Input
The first line contains one integer n (0 ≤ n ≤ 109) without leading zeroes. The second lines contains one integer m (0 ≤ m ≤ 109) — Bob's answer, possibly with leading zeroes.
Output
Print OK if Bob's answer is correct and WRONG_ANSWER otherwise.

Vasya adores sport programming. He can't write programs but he loves to watch the contests' progress. Vasya even has a favorite coder and Vasya pays special attention to him.
One day Vasya decided to collect the results of all contests where his favorite coder participated and track the progress of his coolness. For each contest where this coder participated, he wrote out a single non-negative number — the number of points his favorite coder earned in the contest. Vasya wrote out the points for the contest in the order, in which the contests run (naturally, no two contests ran simultaneously).
Vasya considers a coder's performance in a contest amazing in two situations: he can break either his best or his worst performance record. First, it is amazing if during the contest the coder earns strictly more points that he earned on each past contest. Second, it is amazing if during the contest the coder earns strictly less points that he earned on each past contest. A coder's first contest isn't considered amazing. Now he wants to count the number of amazing performances the coder had throughout his whole history of participating in contests. But the list of earned points turned out long and Vasya can't code... That's why he asks you to help him.
Input
The first line contains the single integer n (1 ≤ n ≤ 1000) — the number of contests where the coder participated.
The next line contains n space-separated non-negative integer numbers — they are the points which the coder has earned. The points are given in the chronological order. All points do not exceed 10000.
Output
Print the single number — the number of amazing performances the coder has had during his whole history of participating in the contests.
