akhauriyash/Code-Regression huggingface dataset:
You have a string S consisting of N uppercase English letters. You are allowed to perform at most one operation of following kind: Choose any position in the string, remove the character at that position and insert it back to any other place in the string.

Find the  lexicographically smallest  string you can achieve.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows.
The first line of each test case contains the single integer N denoting length of string S.
The second line contains the string S.

-----Output-----
For each test case, output a single line containing the answer to the corresponding test case.

-----Constraints-----
- 1 ≤ T ≤ 50
- 1 ≤ N ≤ 50
- S will consist of uppercase English letters.

-----Example-----
Input:
2
4
DCBA
7
XYZZYZZ

Output:
ADCB
XYYZZZZ

-----Explanation-----
Example case 1. The optimal solution here is to choose the last character and put it in the beginning of the string. So the answer will be ADCB
Example case 2. The optimal solution here is to choose the 5-th character (1-based index) and put it between the 2-nd and the 3-rd characters. So the answer will be XYYZZZZ

The statement of this problem is the same as the statement of problem C2. The only difference is that, in problem C1, $n$ is always even, and in C2, $n$ is always odd.

You are given a regular polygon with $2 \cdot n$ vertices (it's convex and has equal sides and equal angles) and all its sides have length $1$. Let's name it as $2n$-gon.

Your task is to find the square of the minimum size such that you can embed $2n$-gon in the square. Embedding $2n$-gon in the square means that you need to place $2n$-gon in the square in such way that each point which lies inside or on a border of $2n$-gon should also lie inside or on a border of the square.

You can rotate $2n$-gon and/or the square.


-----Input-----

The first line contains a single integer $T$ ($1 \le T \le 200$) — the number of test cases.

Next $T$ lines contain descriptions of test cases — one per line. Each line contains single even integer $n$ ($2 \le n \le 200$). Don't forget you need to embed $2n$-gon, not an $n$-gon.


-----Output-----

Print $T$ real numbers — one per test case. For each test case, print the minimum length of a side of the square $2n$-gon can be embedded in. Your answer will be considered correct if its absolute or relative error doesn't exceed $10^{-6}$.

Two sisters, A and B, play the piano every day. During the day, they can play in any order. That is, A might play first and then B, or it could be B first and then A. But each one of them plays the piano exactly once per day. They maintain a common log, in which they write their name whenever they play.
You are given the entries of the log, but you're not sure if it has been tampered with or not. Your task is to figure out whether these entries could be valid or not.

-----Input-----
- The first line of the input contains an integer $T$ denoting the number of test cases. The description of the test cases follows.
- The first line of each test case contains a string $s$ denoting the entries of the log.

-----Output-----
- For each test case, output yes or no according to the answer to the problem.

-----Constraints-----
- $1 \le T \le 500$
- $2 \le |s| \le 100$
- $|s|$ is even
- Each character of $s$ is either 'A' or 'B'

-----Example Input-----
4
AB
ABBA
ABAABB
AA

-----Example Output-----
yes
yes
no
no

-----Explanation-----
Testcase 1: There is only one day, and both A and B have played exactly once. So this is a valid log. Hence 'yes'.
Testcase 2: On the first day, A has played before B, and on the second day, B has played first. Hence, this is also a valid log.
Testcase 3: On the first day, A played before B, but on the second day, A seems to have played twice. This cannot happen, and hence this is 'no'.

Given an array $A_1, A_2, ..., A_N$, count the number of subarrays of array $A$ which are non-decreasing.

A subarray $A[i, j]$, where $1 ≤ i ≤ j ≤ N$ is a sequence of integers $A_i, A_i+1, ..., A_j$.
A subarray $A[i, j]$ is non-decreasing if $A_i ≤ A_i+1 ≤ A_i+2 ≤ ... ≤ A_j$. You have to count the total number of such subarrays.

-----Input-----
- 
The first line of input contains an integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- 
The first line of each test case contains a single integer $N$ denoting the size of array.
- 
The second line contains $N$ space-separated integers $A_1$, $A_2$, …, $A_N$ denoting the elements of the array.

-----Output-----
For each test case, output in a single line the required answer.

-----Constraints-----
- $1 ≤ T ≤ 5$
- $1 ≤ N ≤ 10^5$
- $1 ≤ A_i ≤ 10^9$

-----Subtasks-----
- Subtask 1 (20 points) : $1 ≤ N ≤ 100$
- Subtask 2 (30 points) : $1 ≤ N ≤ 1000$
- Subtask 3 (50 points) : Original constraints

-----Sample Input:-----
2
4
1 4 2 3
1
5

-----Sample Output:-----
6
1

-----Explanation-----
Example case 1.

All valid subarrays are $A[1, 1], A[1, 2], A[2, 2], A[3, 3], A[3, 4], A[4, 4]$.

Note that singleton subarrays are identically non-decreasing.
Example case 2.

Only single subarray $A[1, 1]$ is non-decreasing.

The XOR pair representation (XPR) of a positive integer $N$ is defined as a pair of integers $(A, B)$ such that:
- $1 \le A \le B \le N$
- $A \oplus B = N$
- if there is no way to choose $A$ and $B$ satisfying the above conditions, $A = B = -1$
- otherwise, the value of $A$ should be the smallest possible
These conditions uniquely define the XPR. Next, we define a function $F(N)$ = the value of $B$ in $XPR(N)$, and a function $G(L, R) = \sum\limits_{i=L}^R F(i)$.
You are given $L$ and $R$. Compute $G(L, R)$.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first and only line of each test case contains two space-separated integers $L$ and $R$.

-----Output-----
For each test case, print a single line containing one integer — the value of the function $G(L, R)$.

-----Constraints-----
- $1 \le T \le 10^5$
- $1 \le L \le R \le 10^9$

 u(n) is the smallest prime number strictly greater than n. 

Find $\sum_{i = 2}^{n} \frac{1}{v(i) u(i)}$.


-----Input-----

The first line contains integer t (1 ≤ t ≤ 500) — the number of testscases. 

Each of the following t lines of the input contains integer n (2 ≤ n ≤ 10^9).


-----Output-----

Print t lines: the i-th of them must contain the answer to the i-th test as an irreducible fraction "p/q", where p, q are integers, q > 0.

Mance Rayder, the King-Beyond-the-Wall, has always wanted to lead the largest army the North has ever seen against the NIght’s Watch. For this humungous feat he has banded the waring tribes, the Giants, Thenns and Wildings, together by going to great extents. But the King is facing with an issue he always saw it coming.
The huge army is divided into smaller divisions and each division can be of the type $G, T$ or $W$ standing for Giants, Thenns and Wildings respectively. Mance doesn’t want two divisions of the same type standing together as he fears it might lead to a mutiny or an unorganised charge or retreat. 
For a given numbers of $G, T$ and $W$, find whether an army can be organised in accordance to the rules set by Mance. Not to forget that Mance has to include all the divisions in his battle formation in order to stand a chance against the Wall’s defences.

-----Input:-----
- First line will contain $N$, the number of test cases.
- Each of the next $N$ lines will contain three integers $G$, $T$ and $W$ - the number of Giant, Thenn and Wildling divisions respectively.

-----Output:-----
For each testcase, output in a single line $Yes$ if a battle formation is possible or $No$ otherwise.

-----Constraints-----
- $1 \leq N \leq 100$
- $1 \leq G,T,W \leq 10^9$

-----Sample Input:-----
1
1 2 1

-----Sample Output:-----
Yes

-----Explanation:-----
The first case can be formed as : $ TGWT $. Hence the answer is $ Yes $.

You are given an array a with n distinct integers. Construct an array b by permuting a such that for every non-empty subset of indices S = {x_1, x_2, ..., x_{k}} (1 ≤ x_{i} ≤ n, 0 < k < n) the sums of elements on that positions in a and b are different, i. e. $\sum_{i = 1}^{k} a_{x_{i}} \neq \sum_{i = 1}^{k} b_{x_{i}}$


-----Input-----

The first line contains one integer n (1 ≤ n ≤ 22) — the size of the array.

The second line contains n space-separated distinct integers a_1, a_2, ..., a_{n} (0 ≤ a_{i} ≤ 10^9) — the elements of the array.


-----Output-----

If there is no such array b, print -1.

Otherwise in the only line print n space-separated integers b_1, b_2, ..., b_{n}. Note that b must be a permutation of a.

If there are multiple answers, print any of them.

Chef likes problems which using some math. Now he asks you to solve next one. You have 4 integers, Chef wondering is there non-empty subset which has sum equals 0.

-----Input-----
The first line of input contains T - number of test cases. 
Each of the next T lines containing four pairwise distinct integer numbers - a, b, c, d.

-----Output-----
For each test case output "Yes", if possible to get 0 by choosing non-empty subset of {a, b, c, d} with sum equal 0, or "No" in another case.

-----Constraints-----
- 1 ≤ T ≤ 103
- -106 ≤ a, b, c, d ≤ 106 

-----Example-----
Input:
3
1 2 0 3
1 2 4 -1
1 2 3 4

Output:
Yes
Yes
No

-----Explanation-----
Example case 1. We can choose subset {0} 
Example case 2. We can choose subset {-1, 1}

The chef is trying to solve some pattern problems, Chef wants your help to code it. Chef has one number K to form a new pattern. Help the chef to code this pattern problem.

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- Each test case contains a single line of input, one integer $K$. 

-----Output:-----
For each test case, output as the pattern.

-----Constraints-----
- $1 \leq T \leq 50$
- $1 \leq K \leq 50$

-----Sample Input:-----
5
1
2
3
4
5

-----Sample Output:-----
*
*
***
*
* *
*****
*
* *
*   *
*******
*
* *
*   *
*     *
*********   

-----EXPLANATION:-----
No need, else pattern can be decode easily.
