Provide tags and a correct Python 3 solution for this coding contest problem.
A boy Valera registered on site Codeforces as Valera, and wrote his first Codeforces Round #300. He boasted to a friend Arkady about winning as much as x points for his first contest. But Arkady did not believe his friend's words and decided to check whether Valera could have shown such a result.
He knows that the contest number 300 was unusual because there were only two problems. The contest lasted for t minutes, the minutes are numbered starting from zero. The first problem had the initial cost of a points, and every minute its cost reduced by da points. The second problem had the initial cost of b points, and every minute this cost reduced by db points. Thus, as soon as the zero minute of the contest is over, the first problem will cost a - da points, and the second problem will cost b - db points. It is guaranteed that at any moment of the contest each problem has a non-negative cost.
Arkady asks you to find out whether Valera could have got exactly x points for this contest. You should assume that Valera could have solved any number of the offered problems. You should also assume that for each problem Valera made no more than one attempt, besides, he could have submitted both problems at the same minute of the contest, starting with minute 0 and ending with minute number t - 1. Please note that Valera can't submit a solution exactly t minutes after the start of the contest or later.
Input
The single line of the input contains six integers x, t, a, b, da, db (0 ≤ x ≤ 600; 1 ≤ t, a, b, da, db ≤ 300) — Valera's result, the contest's duration, the initial cost of the first problem, the initial cost of the second problem, the number of points that the first and the second problem lose per minute, correspondingly.
It is guaranteed that at each minute of the contest each problem has a non-negative cost, that is, a - i·da ≥ 0 and b - i·db ≥ 0 for all 0 ≤ i ≤ t - 1.
Output
If Valera could have earned exactly x points at a contest, print "YES", otherwise print "NO" (without the quotes).
Examples
Input
30 5 20 20 3 5
Output
YES
Input
10 4 100 5 5 1
Output
NO
Note
In the first sample Valera could have acted like this: he could have submitted the first problem at minute 0 and the second problem — at minute 2. Then the first problem brings him 20 points and the second problem brings him 10 points, that in total gives the required 30 points. | instruction | 0 | 71,936 | 11 | 143,872 |

Correct Solution:
```
x,t,a,b,c,d=map(int,input().split())
R=range(t)
y=x==0
for i in R:
if x==a-c*i or x==b-d*i:y=1
for j in R:y|=x==a+b-c*i-d*j
print(['NO','YES'][y])

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A boy Valera registered on site Codeforces as Valera, and wrote his first Codeforces Round #300. He boasted to a friend Arkady about winning as much as x points for his first contest. But Arkady did not believe his friend's words and decided to check whether Valera could have shown such a result.
He knows that the contest number 300 was unusual because there were only two problems. The contest lasted for t minutes, the minutes are numbered starting from zero. The first problem had the initial cost of a points, and every minute its cost reduced by da points. The second problem had the initial cost of b points, and every minute this cost reduced by db points. Thus, as soon as the zero minute of the contest is over, the first problem will cost a - da points, and the second problem will cost b - db points. It is guaranteed that at any moment of the contest each problem has a non-negative cost.
Arkady asks you to find out whether Valera could have got exactly x points for this contest. You should assume that Valera could have solved any number of the offered problems. You should also assume that for each problem Valera made no more than one attempt, besides, he could have submitted both problems at the same minute of the contest, starting with minute 0 and ending with minute number t - 1. Please note that Valera can't submit a solution exactly t minutes after the start of the contest or later.
Input
The single line of the input contains six integers x, t, a, b, da, db (0 ≤ x ≤ 600; 1 ≤ t, a, b, da, db ≤ 300) — Valera's result, the contest's duration, the initial cost of the first problem, the initial cost of the second problem, the number of points that the first and the second problem lose per minute, correspondingly.
It is guaranteed that at each minute of the contest each problem has a non-negative cost, that is, a - i·da ≥ 0 and b - i·db ≥ 0 for all 0 ≤ i ≤ t - 1.
Output
If Valera could have earned exactly x points at a contest, print "YES", otherwise print "NO" (without the quotes).
Examples
Input
30 5 20 20 3 5
Output
YES
Input
10 4 100 5 5 1
Output
NO
Note
In the first sample Valera could have acted like this: he could have submitted the first problem at minute 0 and the second problem — at minute 2. Then the first problem brings him 20 points and the second problem brings him 10 points, that in total gives the required 30 points.

In the year 2168, AtCoder Inc., which is much larger than now, is starting a limited express train service called AtCoder Express.
In the plan developed by the president Takahashi, the trains will run as follows:
* A train will run for (t_1 + t_2 + t_3 + ... + t_N) seconds.
* In the first t_1 seconds, a train must run at a speed of at most v_1 m/s (meters per second). Similarly, in the subsequent t_2 seconds, a train must run at a speed of at most v_2 m/s, and so on.
According to the specifications of the trains, the acceleration of a train must be always within ±1m/s^2. Additionally, a train must stop at the beginning and the end of the run.
Find the maximum possible distance that a train can cover in the run.
Constraints
* 1 \leq N \leq 100
* 1 \leq t_i \leq 200
* 1 \leq v_i \leq 100
* All input values are integers.
Input
Input is given from Standard Input in the following format:

Berland crossword is a puzzle that is solved on a square grid with n rows and n columns. Initially all the cells are white.
To solve the puzzle one has to color some cells on the border of the grid black in such a way that:
* exactly U cells in the top row are black;
* exactly R cells in the rightmost column are black;
* exactly D cells in the bottom row are black;
* exactly L cells in the leftmost column are black.
Note that you can color zero cells black and leave every cell white.
Your task is to check if there exists a solution to the given puzzle.
Input
The first line contains a single integer t (1 ≤ t ≤ 1000) — the number of testcases.
Then the descriptions of t testcases follow.
The only line of each testcase contains 5 integers n, U, R, D, L (2 ≤ n ≤ 100; 0 ≤ U, R, D, L ≤ n).
Output
For each testcase print "YES" if the solution exists and "NO" otherwise.
You may print every letter in any case you want (so, for example, the strings yEs, yes, Yes and YES are all recognized as positive answer).
Example
Input
4
5 2 5 3 1
3 0 0 0 0
4 4 1 4 0
2 1 1 1 1
Output
YES
YES
NO
YES
Note
Here are possible solutions to testcases 1, 2 and 4:

Provide tags and a correct Python 3 solution for this coding contest problem.
The marmots have prepared a very easy problem for this year's HC2 – this one. It involves numbers n, k and a sequence of n positive integers a1, a2, ..., an. They also came up with a beautiful and riveting story for the problem statement. It explains what the input means, what the program should output, and it also reads like a good criminal.
However I, Heidi, will have none of that. As my joke for today, I am removing the story from the statement and replacing it with these two unhelpful paragraphs. Now solve the problem, fools!
Input
The first line of the input contains two space-separated integers n and k (1 ≤ k ≤ n ≤ 2200). The second line contains n space-separated integers a1, ..., an (1 ≤ ai ≤ 104).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The marmots have prepared a very easy problem for this year's HC2 – this one. It involves numbers n, k and a sequence of n positive integers a1, a2, ..., an. They also came up with a beautiful and riveting story for the problem statement. It explains what the input means, what the program should output, and it also reads like a good criminal.
However I, Heidi, will have none of that. As my joke for today, I am removing the story from the statement and replacing it with these two unhelpful paragraphs. Now solve the problem, fools!
Input
The first line of the input contains two space-separated integers n and k (1 ≤ k ≤ n ≤ 2200). The second line contains n space-separated integers a1, ..., an (1 ≤ ai ≤ 104).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This is an interactive problem. Refer to the Interaction section below for better understanding.
Ithea and Chtholly want to play a game in order to determine who can use the kitchen tonight.
<image>
Initially, Ithea puts n clear sheets of paper in a line. They are numbered from 1 to n from left to right.
This game will go on for m rounds. In each round, Ithea will give Chtholly an integer between 1 and c, and Chtholly needs to choose one of the sheets to write down this number (if there is already a number before, she will erase the original one and replace it with the new one).
Chtholly wins if, at any time, all the sheets are filled with a number and the n numbers are in non-decreasing order looking from left to right from sheet 1 to sheet n, and if after m rounds she still doesn't win, she loses the game.
Chtholly really wants to win the game as she wants to cook something for Willem. But she doesn't know how to win the game. So Chtholly finds you, and your task is to write a program to receive numbers that Ithea gives Chtholly and help her make the decision on which sheet of paper write this number.
Input
The first line contains 3 integers n, m and c (<image>, <image> means <image> rounded up) — the number of sheets, the number of rounds and the largest possible number Ithea can give to Chtholly respectively. The remaining parts of input are given throughout the interaction process.
Interaction
In each round, your program needs to read one line containing a single integer pi (1 ≤ pi ≤ c), indicating the number given to Chtholly.
Your program should then output a line containing an integer between 1 and n, indicating the number of sheet to write down this number in.
After outputting each line, don't forget to flush the output. For example:
* fflush(stdout) in C/C++;
* System.out.flush() in Java;
* sys.stdout.flush() in Python;
* flush(output) in Pascal;
* See the documentation for other languages.
If Chtholly wins at the end of a round, no more input will become available and your program should terminate normally. It can be shown that under the constraints, it's always possible for Chtholly to win the game.
Example
Input
2 4 4
2
1
3
Output
1
2
2
Note
In the example, Chtholly initially knew there were 2 sheets, 4 rounds and each number was between 1 and 4. She then received a 2 and decided to write it in the 1st sheet. Then she received a 1 and wrote it in the 2nd sheet. At last, she received a 3 and replaced 1 with 3 in the 2nd sheet. At this time all the sheets were filled with a number and they were non-decreasing, so she won the game.
Note that it is required that your program terminate immediately after Chtholly wins and do not read numbers from the input for the remaining rounds. If not, undefined behaviour may arise and it won't be sure whether your program will be accepted or rejected. Also because of this, please be careful when hacking others' codes. In the sample, Chtholly won the game after the 3rd round, so it is required that your program doesn't read the number of the remaining 4th round.
The input format for hacking:
* The first line contains 3 integers n, m and c;
* The following m lines each contains an integer between 1 and c, indicating the number given to Chtholly in each round.
Submitted Solution:
```
import sys
n, m, c = map(int, input().split())
free = n
nums = [0] * n
for i in range(m):
pi = int(input())
if(pi > c//2):
current = n - 1
while(nums[current] > 0 and nums[current] >= pi and current >= 0):current -= 1
if(current == -1):current = 0
if(nums[current] == 0):free -= 1
nums[current] = pi
print(current + 1)
else:
current = 0
while(current < n and nums[current] > 0 and nums[current] <= pi):current += 1
if(current == n):current = n - 1
if(nums[current] == 0):free -=1
nums[current] = pi
print(current + 1)
if(free == 0):break
