As lockdown is going on so no is allowed to go outside , so Chef has come with an innovative idea for food home delivery using drone.  But there is an issue with it , the drone can move forward or backward a fix number of steps $x$ . 
All the houses and chef restaurant are all in a straight line . Homes which need delivery are located at $H[i]$ and chef is located at $y$ coordinate . 
If Drone is at a location $R$, then it can move to $R-x$ or $R+x$ . 
Help chef find maximum value of $x$ to complete all the deliveries as he is busy managing the orders.

-----Input:-----
- First line will contain $n$ and $R$, number of houses that need delivery and the correct coordinate of chef (Drone).
- Second line contains $n$ integers , the coordinate of all homes that need delivery. 

-----Output:-----
- The maximum value of $x$ , so that drone delivers to all houses.

-----Constraints-----
- $1 \leq n \leq 1000$
- $1 \leq R \leq 10^9$
- $1 \leq hi \leq 10^9$
- $1 \leq x  \leq 10^9$

-----Sample Input:-----
3 1
3 5 11

-----Sample Output:-----
2

-----EXPLANATION:-----
Chef's drone is at 1 initially and he needs to visit 3,5,11 , so optimal solution will be (maximum value of x ) equal to 2.

Every day, Mike goes to his job by a bus, where he buys a ticket. On the ticket, there is a letter-code that can be represented as a string of upper-case Latin letters.
Mike believes that the day will be successful in case exactly two different letters in the code alternate.  Otherwise, he believes that the day will be unlucky. Please see note section for formal definition of alternating code.
You are given a ticket code. Please determine, whether the day will be successful for Mike or not. Print "YES" or "NO" (without quotes) corresponding to the situation.

-----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 and only line of each test case contains a single string S denoting the letter code on the ticket.

-----Output-----
For each test case, output a single line containing "YES" (without quotes) in case the day will be successful and "NO" otherwise.

-----Note-----
Two letters x, y where x != y are said to be alternating in a code, if code is of form "xyxyxy...".

-----Constraints-----

- 1 ≤ T ≤ 100
- S consists only of upper-case Latin letters

Subtask 1 (50 points):

- |S| = 2

Subtask 2 (50 points):

- 2 ≤ |S| ≤ 100

-----Example-----
Input:
2
ABABAB
ABC

Output:
YES
NO

There is a popular apps named “Exbook” like “Facebook”. To sign up in this app , You have to make a strong password with more than 3 digits and less than 10 digits . But I am a pro hacker and so I make a Exbook hacking site . You need to login in this site to hack exbook account and then you will get a portal. You can give any user exbook login link using this site and when anyone login into exbook using your link ,you can see his/her password .
But I made a mistake and so you cannot find original password in your portal . The portal showing you by adding two in every digit . So , now you have to find out the original password of an user if I give you the password which is showing in your portal .

-----Input:-----
The first line contains a single integer t (1 ≤ t ≤ 1000) — the number of test cases.
The first line of each test case contains a single integer n which is showing in your portal . Mind it , every digit of n is greater than one .

-----Output:-----
Print , original password of user .

Being a crewmate in the Among Us game, you will have to solve a task to win against the imposter. 
The task : You are given a certain number of bulbs(Say n) which are initially in OFF position. 
The bulbs are numbered from 1 to n. There will be n current fluctuations in such a way that in the 1st fluctuation all bulbs are toggled, in the 2nd fluctuation every 2nd bulb is toggled, in the 3rd fluctuation every 3rd bulb is toggled and so on.
Your job as a crewmate is to find the number of bulbs which are ON at the end of n fluctuations. But, the imposter has a special power which alerts it when a bulb with a number divisible by 3 is kept ON at the end of n fluctuations. 
So, you will have to switch off the bulbs with numbers divisible by 3 and give the final result to complete the task and win the game.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, an integer $n$. 

-----Output:-----
- For each testcase, output a single integer - the number of bulbs that will remain ON after $n$ fluctuations.

-----Constraints :-----
- $1 \leq T \leq 1000$
- $2 \leq n \leq 10^9$

In order to celebrate Twice's 5th anniversary, Tzuyu and Sana decided to play a game.

Tzuyu gave Sana two integers $a$ and $b$ and a really important quest.

In order to complete the quest, Sana has to output the smallest possible value of ($a \oplus x$) + ($b \oplus x$) for any given $x$, where $\oplus$ denotes the bitwise XOR operation. 


-----Input-----

Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 10^{4}$). Description of the test cases follows.

The only line of each test case contains two integers $a$ and $b$ ($1 \le a, b \le 10^{9}$).


-----Output-----

For each testcase, output the smallest possible value of the given expression.


-----Example-----
Input
6
6 12
4 9
59 832
28 14
4925 2912
1 1

Output
10
13
891
18
6237
0



-----Note-----

For the first test case Sana can choose $x=4$ and the value will be ($6 \oplus 4$) + ($12 \oplus 4$) = $2 + 8$ = $10$. It can be shown that this is the smallest possible value.

Tavak and Seyyed are good friends. Seyyed is very funny and he told Tavak to solve the following problem instead of longest-path.

You are given l and r. For all integers from l to r, inclusive, we wrote down all of their integer divisors except 1. Find the integer that we wrote down the maximum number of times.

Solve the problem to show that it's not a NP problem.


-----Input-----

The first line contains two integers l and r (2 ≤ l ≤ r ≤ 10^9).


-----Output-----

Print single integer, the integer that appears maximum number of times in the divisors. 

If there are multiple answers, print any of them.


-----Examples-----
Input
19 29

Output
2

Input
3 6

Output
3



-----Note-----

Definition of a divisor: https://www.mathsisfun.com/definitions/divisor-of-an-integer-.html

The first example: from 19 to 29 these numbers are divisible by 2: {20, 22, 24, 26, 28}.

The second example: from 3 to 6 these numbers are divisible by 3: {3, 6}.

The values of D_i are all distinct.
Does a tree with N vertices that satisfies the following conditions exist?
 - The vertices are numbered 1,2,..., N.
 - The edges are numbered 1,2,..., N-1, and Edge i connects Vertex u_i and v_i.
 - For each vertex i, the sum of the distances from i to the other vertices is D_i, assuming that the length of each edge is 1.
If such a tree exists, construct one such tree.

-----Constraints-----
 - 2 \leq N \leq 100000
 - 1 \leq D_i \leq 10^{12}
 - D_i are all distinct.

-----Input-----
Input is given from Standard Input in the following format:
N
D_1
D_2
:
D_N

-----Output-----
If a tree with n vertices that satisfies the conditions does not exist, print -1.
If a tree with n vertices that satisfies the conditions exist, print n-1 lines.
The i-th line should contain u_i and v_i with a space in between.
If there are multiple trees that satisfy the conditions, any such tree will be accepted.

-----Sample Output-----

The tree shown below satisfies the conditions.

Shaun is very much interested in Subarrays. Shaun wants to count the number of subarrays in his chosen array with sum being a multiple of $10^9$. Since, Shaun is interested in huge numbers.He chose his array such that it contains only $10^8$ and $9*10^8$ as its elements.
Help shaun to count the number of required subarrays.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- First line of each testcase contains one integer $N$,size of array $A$. 
- Second line of each testcase contains $N$ space separated array elements

-----Output:-----
For each testcase, output in a single line number of subarrays with sum being multiple of $10^9$.

-----Constraints-----
- $1 \leq T \leq 10$
- $1 \leq N \leq 10^5$
- $A[i]$=$10^8$ , $9*10^8$

-----Sample Input:-----

3
100000000 900000000 100000000
1
900000000

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