One day Anna got the following task at school: to arrange several numbers in a circle so that any two neighboring numbers differs exactly by 1. Anna was given several numbers and arranged them in a circle to fulfill the task. Then she wanted to check if she had arranged the numbers correctly, but at this point her younger sister Maria came and shuffled all numbers. Anna got sick with anger but what's done is done and the results of her work had been destroyed. But please tell Anna: could she have hypothetically completed the task using all those given numbers?
Input
The first line contains an integer n β how many numbers Anna had (3 β€ n β€ 105). The next line contains those numbers, separated by a space. All numbers are integers and belong to the range from 1 to 109.
Output
Print the single line "YES" (without the quotes), if Anna could have completed the task correctly using all those numbers (using all of them is necessary). If Anna couldn't have fulfilled the task, no matter how hard she would try, print "NO" (without the quotes).

Programmers working on a large project have just received a task to write exactly m lines of code. There are n programmers working on a project, the i-th of them makes exactly ai bugs in every line of code that he writes.
Let's call a sequence of non-negative integers v1, v2, ..., vn a plan, if v1 + v2 + ... + vn = m. The programmers follow the plan like that: in the beginning the first programmer writes the first v1 lines of the given task, then the second programmer writes v2 more lines of the given task, and so on. In the end, the last programmer writes the remaining lines of the code. Let's call a plan good, if all the written lines of the task contain at most b bugs in total.
Your task is to determine how many distinct good plans are there. As the number of plans can be large, print the remainder of this number modulo given positive integer mod.
Input
The first line contains four integers n, m, b, mod (1 β€ n, m β€ 500, 0 β€ b β€ 500; 1 β€ mod β€ 109 + 7) β the number of programmers, the number of lines of code in the task, the maximum total number of bugs respectively and the modulo you should use when printing the answer.
The next line contains n space-separated integers a1, a2, ..., an (0 β€ ai β€ 500) β the number of bugs per line for each programmer.
Output
Print a single integer β the answer to the problem modulo mod.

Programmers working on a large project have just received a task to write exactly m lines of code. There are n programmers working on a project, the i-th of them makes exactly ai bugs in every line of code that he writes.
Let's call a sequence of non-negative integers v1, v2, ..., vn a plan, if v1 + v2 + ... + vn = m. The programmers follow the plan like that: in the beginning the first programmer writes the first v1 lines of the given task, then the second programmer writes v2 more lines of the given task, and so on. In the end, the last programmer writes the remaining lines of the code. Let's call a plan good, if all the written lines of the task contain at most b bugs in total.
Your task is to determine how many distinct good plans are there. As the number of plans can be large, print the remainder of this number modulo given positive integer mod.
Input
The first line contains four integers n, m, b, mod (1 β€ n, m β€ 500, 0 β€ b β€ 500; 1 β€ mod β€ 109 + 7) β the number of programmers, the number of lines of code in the task, the maximum total number of bugs respectively and the modulo you should use when printing the answer.
The next line contains n space-separated integers a1, a2, ..., an (0 β€ ai β€ 500) β the number of bugs per line for each programmer.
Output
Print a single integer β the answer to the problem modulo mod.

Programmers working on a large project have just received a task to write exactly m lines of code. There are n programmers working on a project, the i-th of them makes exactly ai bugs in every line of code that he writes.
Let's call a sequence of non-negative integers v1, v2, ..., vn a plan, if v1 + v2 + ... + vn = m. The programmers follow the plan like that: in the beginning the first programmer writes the first v1 lines of the given task, then the second programmer writes v2 more lines of the given task, and so on. In the end, the last programmer writes the remaining lines of the code. Let's call a plan good, if all the written lines of the task contain at most b bugs in total.
Your task is to determine how many distinct good plans are there. As the number of plans can be large, print the remainder of this number modulo given positive integer mod.
Input
The first line contains four integers n, m, b, mod (1 β€ n, m β€ 500, 0 β€ b β€ 500; 1 β€ mod β€ 109 + 7) β the number of programmers, the number of lines of code in the task, the maximum total number of bugs respectively and the modulo you should use when printing the answer.
The next line contains n space-separated integers a1, a2, ..., an (0 β€ ai β€ 500) β the number of bugs per line for each programmer.
Output
Print a single integer β the answer to the problem modulo mod.

You are an upcoming movie director, and you have just released your first movie. You have also launched a simple review site with two buttons to press β upvote and downvote.
However, the site is not so simple on the inside. There are two servers, each with its separate counts for the upvotes and the downvotes.
n reviewers enter the site one by one. Each reviewer is one of the following types:
* type 1: a reviewer has watched the movie, and they like it β they press the upvote button;
* type 2: a reviewer has watched the movie, and they dislike it β they press the downvote button;
* type 3: a reviewer hasn't watched the movie β they look at the current number of upvotes and downvotes of the movie on the server they are in and decide what button to press. If there are more downvotes than upvotes, then a reviewer downvotes the movie. Otherwise, they upvote the movie.
Each reviewer votes on the movie exactly once.
Since you have two servers, you can actually manipulate the votes so that your movie gets as many upvotes as possible. When a reviewer enters a site, you know their type, and you can send them either to the first server or to the second one.
What is the maximum total number of upvotes you can gather over both servers if you decide which server to send each reviewer to?
Input
The first line contains a single integer t (1 β€ t β€ 10^4) β the number of testcases.
Then the descriptions of t testcases follow.
The first line of each testcase contains a single integer n (1 β€ n β€ 50) β the number of reviewers.
The second line of each testcase contains n integers r_1, r_2, ..., r_n (1 β€ r_i β€ 3) β the types of the reviewers in the same order they enter the site.
Output
For each testcase print a single integer β the maximum total number of upvotes you can gather over both servers if you decide which server to send each reviewer to.

In the second testcase of the example you can send all reviewers to the first server:
* the first reviewer upvotes;
* the second reviewer downvotes;
* the last reviewer sees that the number of downvotes is not greater than the number of upvotes β upvote themselves.
There are two upvotes in total. Alternatevely, you can send the first and the second reviewers to the first server and the last reviewer β to the second server:
* the first reviewer upvotes on the first server;
* the second reviewer downvotes on the first server;
* the last reviewer sees no upvotes or downvotes on the second server β upvote themselves.

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 β€ id β€ 106) β 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 β the number of the subject the given document corresponds to.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Limak is going to participate in a contest on the last day of the 2016. The contest will start at 20:00 and will last four hours, exactly until midnight. There will be n problems, sorted by difficulty, i.e. problem 1 is the easiest and problem n is the hardest. Limak knows it will take him 5Β·i minutes to solve the i-th problem.
Limak's friends organize a New Year's Eve party and Limak wants to be there at midnight or earlier. He needs k minutes to get there from his house, where he will participate in the contest first.
How many problems can Limak solve if he wants to make it to the party?
Input
The only line of the input contains two integers n and k (1 β€ n β€ 10, 1 β€ k β€ 240) β the number of the problems in the contest and the number of minutes Limak needs to get to the party from his house.
Output
Print one integer, denoting the maximum possible number of problems Limak can solve so that he could get to the party at midnight or earlier.

Note
In the first sample, there are 3 problems and Limak needs 222 minutes to get to the party. The three problems require 5, 10 and 15 minutes respectively. Limak can spend 5 + 10 = 15 minutes to solve first two problems. Then, at 20:15 he can leave his house to get to the party at 23:57 (after 222 minutes). In this scenario Limak would solve 2 problems. He doesn't have enough time to solve 3 problems so the answer is 2.
In the second sample, Limak can solve all 4 problems in 5 + 10 + 15 + 20 = 50 minutes. At 20:50 he will leave the house and go to the party. He will get there exactly at midnight.
In the third sample, Limak needs only 1 minute to get to the party. He has enough time to solve all 7 problems.
