Richik$Richik$ has just completed his engineering and has got a job in one of the firms at Sabrina$Sabrina$ which is ranked among the top seven islands in the world in terms of the pay scale. 
Since Richik$Richik$ has to travel a lot to reach the firm, the owner assigns him a number X$X$, and asks him to come to work only on the day which is a multiple of X$X$. Richik joins the firm on 1-st day but starts working from X-th day. Richik$Richik$ is paid exactly the same amount in Dollars as the day number. For example, if Richik$Richik$ has been assigned X=3$X = 3$, then he will be paid 3$3$ dollars and 6$6$ dollars on the 3rd$3rd$ and 6th$6th$ day on which he comes for work. 
On N−th$N-th$ day, the owner calls up Richik$Richik$ and asks him not to come to his firm anymore. Hence Richik$Richik$ demands his salary of all his working days together. Since it will take a lot of time to add, Richik$Richik$ asks help from people around him, let's see if you can help him out. 

-----Input:-----
- First line will contain T$T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, two integers X,N$X, N$. 

-----Output:-----
For each testcase, output in a single line which is the salary which Richik$Richik$ demands. 

-----Constraints-----
- 1≤T≤1000$1 \leq T \leq 1000$
- 1≤X<=N≤107$1 \leq X<=N \leq 10^7$

You are given a string A. Find a string B, where B is a palindrome and A is a subsequence of B.

A subsequence of a string is a string that can be derived from it by deleting some (not necessarily consecutive) characters without changing the order of the remaining characters. For example, "cotst" is a subsequence of "contest".

A palindrome is a string that reads the same forward or backward.

The length of string B should be at most 10^4. It is guaranteed that there always exists such string.

You do not need to find the shortest answer, the only restriction is that the length of string B should not exceed 10^4.


-----Input-----

First line contains a string A (1 ≤ |A| ≤ 10^3) consisting of lowercase Latin letters, where |A| is a length of A.


-----Output-----

Output single line containing B consisting of only lowercase Latin letters. You do not need to find the shortest answer, the only restriction is that the length of string B should not exceed 10^4. If there are many possible B, print any of them.


-----Examples-----
Input
aba

Output
aba
Input
ab

Output
aabaa


-----Note-----

In the first example, "aba" is a subsequence of "aba" which is a palindrome.

In the second example, "ab" is a subsequence of "aabaa" which is a palindrome.

Mr. Pr and Ms. Ad are at $a$ and $b$ respectively on an infinite number line. Mr. Pr wants to meet Ms. Ad.
Mr. Pr can choose to move  $c$ or $d$ units in 1 second. If Mr. Pr moves $c$ units then Ms. Ad will move $d$ units and vice versa. (Both of them always moved in positive x-direction)
You have to determine if Mr. Pr can meet with Ms. Ad after some integral amount of time, given that Mr. Pr chooses optimally. Note that meeting after a fractional amount of time does not count.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains four space separated integers, $a$, $b$, $c$, and $d$.

-----Output:-----
- For each test case, output a single line containing "YES" if Mr. Pr meets with Ms. Ad, otherwise "NO".

-----Constraints-----
- $1 \leq T \leq 10^5$
- $1 \leq a,b,c,d \leq 10^9$

-----Sample Input:-----
2
3 4 1 2
10 20 3 7

-----Sample Output:-----
YES
NO

-----Explanation:-----
In the first test case, Mr. Pr will move 2 units in the first second and Ms. Ad moves 1 unit simultaneously and they meet. 
In the second test case, it is impossible to meet (fractional time is not allowed).

You are given an $array$ of size $N$ and an integer $K$ ( $N > 1 , K > 0$ ).
Each element in the array can be incremented by $K$ or decremented by $K$ $at$ $most$ $once$.
So there will be  $3^n$ possible combinations of final array. (As there are 3 options for every element).

Out of these combinations, you have to select a combination, in which the $absolute$ difference between the largest and the smallest element is $maximum$.
You have to print the $maximum$ $absolute$ $difference$.

Write a program to check whether a triangle is valid or not, when the three angles of the triangle are the inputs. A triangle is valid if the sum of all the three angles is equal to 180 degrees.

-----Input-----

The first line contains an integer T, the total number of testcases. Then T lines follow, each line contains three angles  A, B and C, of the triangle separated by space. 

-----Output-----
For each test case, display 'YES' if the triangle is valid, and 'NO', if it is not, in a new line.

-----Constraints-----
- 1 ≤ T ≤ 1000
- 1 ≤ A,B,C ≤ 180

-----Example-----
Input

3 
40 40 100
45 45 90
180 1 1
Output

YES
YES

Given an alphanumeric string made up of digits and lower case Latin characters only, find the sum of all the digit characters in the string.

-----Input-----
- The first line of the input contains an integer T denoting the number of test cases. Then T test cases follow.
- Each test case is described with a single line containing a string S, the alphanumeric string.

-----Output-----
- For each test case, output a single line containing the sum of all the digit characters in that string.

-----Constraints-----
- 1 ≤ T ≤ 1000
- 1 ≤ |S| ≤ 1000, where |S| is the length of the string S.

-----Example-----
Input:
1
ab1231da

Output:
7

-----Explanation-----
The digits in this string are 1, 2, 3 and 1. Hence, the sum of all of them is 7.

We have a sequence A of N non-negative integers.
Compute the sum of \prod _{i = 1} ^N \dbinom{B_i}{A_i} over all sequences B of N non-negative integers whose sum is at most M, and print it modulo (10^9 + 7).
Here, \dbinom{B_i}{A_i}, the binomial coefficient, denotes the number of ways to choose A_i objects from B_i objects, and is 0 when B_i < A_i.

-----Constraints-----
 - All values in input are integers.
 - 1 \leq N \leq 2000
 - 1 \leq M \leq 10^9
 - 0 \leq A_i \leq 2000

-----Input-----
Input is given from Standard Input in the following format:
N M
A_1 A_2 \ldots A_N

-----Output-----
Print the sum of \prod _{i = 1} ^N \dbinom{B_i}{A_i}, modulo (10^9 + 7).

-----Sample Input-----
3 5
1 2 1

-----Sample Output-----
8

There are four sequences B such that \prod _{i = 1} ^N \dbinom{B_i}{A_i} is at least 1:
 - B = \{1, 2, 1\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{1}{1} \times \dbinom{2}{2} \times \dbinom{1}{1} = 1;
 - B = \{2, 2, 1\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{2}{1} \times \dbinom{2}{2} \times \dbinom{1}{1} = 2;
 - B = \{1, 3, 1\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{1}{1} \times \dbinom{3}{2} \times \dbinom{1}{1} = 3;
 - B = \{1, 2, 2\}, where \prod _{i = 1} ^N \dbinom{B_i}{A_i} = \dbinom{1}{1} \times \dbinom{2}{2} \times \dbinom{2}{1} = 2.
The sum of these is 1 + 2 + 3 + 2 = 8.

Kshitij has recently started solving problems on codechef. As he is real problem solving enthusiast, he wants continuous growth in number of problems solved per day.
He started with $a$  problems on first day. 
He solves $d$ problems more than previous day. But after every $k$ days , he increases $d$ by
$inc$ .
Can you guess how many questions he will solve on $nth $ day ?

-----Input:-----
- First line  contains $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input,five integers $a, d, k, n, inc$. 

-----Output:-----
For each testcase, output in a single line number of questions solved on $nth$ day.

-----Constraints-----
- $1 \leq T \leq 15$
- $1 \leq a \leq 99$
- $1 \leq d \leq 100$
- $1 \leq n \leq 10000$
- $1 \leq k \leq n$
- $0 \leq inc \leq 99$

-----Sample Input:-----
1
1 4 3 8 2

-----Sample Output:-----
43

-----EXPLANATION:-----
The number of questions solved in first 8 days is :
$1$ $5$ $9$ $15$ $21$ $27$ $35$ $43$ .
On first day he solved 1 problem . Here $d$ is  4 for first 3 days.
Then after 3 days $d$ increases by 2 (that is 6).

Leha is a bright mathematician. Today he is investigating whether an integer is divisible by some square number or not.
He has a positive integer X represented as a product of N integers a1, a2, .... aN. He has somehow figured out that there exists some integer P such that the number X is divisible by P2, but he is not able to find such P himself. Can you find it for him? If there are more than one possible values of P possible, you can print any one of them.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. T test cases follow.
The first line of each test case contains one integer N denoting the number of intgers in presentation of X.
The second line contains N space-separated integers a1, a2, .... aN.

-----Output-----
For each test case, output a single integer P deoting the answer for this test case. Note that P must be in range from 2 to 1018 inclusive. It's guaranteed that at least one answer exists. If there are more than one possible answers, print any.

-----Constraints-----
- 1 ≤ T ≤ 5
- 1 ≤ N ≤ 100
- 1 ≤ ai ≤ 1018

-----Subtasks-----
- Subtask 1[19 points]: 1 ≤ a1*a2*...*aN ≤ 106
- Subtask 2[22 points]: 1 ≤ a1*a2*...*aN ≤ 1012
- Subtask 3[23 points]: 1 ≤ ai ≤ 1012
- Subtask 4[36 points]: no additional constraints

-----Example-----
Input:
1
3
21 11 6

Output:
3

-----Explanation-----
Example case 1. X = 21 * 11 * 6 = 1386. It's divisible by 9 which is a square number, as 9 = 32. So P = 3.
