There are $N$ cars (numbered $1$ through $N$) on a circular track with length $N$. For each $i$ ($2 \le i \le N$), the $i$-th of them is at a distance $i-1$ clockwise from car $1$, i.e. car $1$ needs to travel a distance $i-1$ clockwise to reach car $i$. Also, for each valid $i$, the $i$-th car has $f_i$ litres of gasoline in it initially.
You are driving car $1$ in the clockwise direction. To move one unit of distance in this direction, you need to spend $1$ litre of gasoline. When you pass another car (even if you'd run out of gasoline exactly at that point), you steal all its gasoline. Once you do not have any gasoline left, you stop.
What is the total clockwise distance travelled by your car? 

-----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 line of each test case contains a single integer $N$.
- The second line contains $N$ space-separated integers $f_1, f_2, \ldots, f_N$.

-----Output-----
For each test case, print a single line containing one integer ― the total clockwise distance travelled.

-----Constraints-----
- $1 \le T \le 100$
- $1 \le N \le 100$
- $0 \le f_i \le 100$ for each valid $i$

-----Subtasks-----

Andrii is good in Math, but not in Programming. He is asking you to solve following problem: Given an integer number N and two sets of integer A and B. Let set A contain all numbers from 1 to N and set B contain all numbers from N + 1 to 2N. Multiset C contains all sums a + b such that a belongs to A and b belongs to B. Note that multiset may contain several elements with the same values. For example, if N equals to three, then A = {1, 2, 3}, B = {4, 5, 6} and C = {5, 6, 6, 7, 7, 7, 8, 8, 9}. Andrii has M queries about multiset C. Every query is defined by a single integer q. Andrii wants to know the number of times q is contained in C. For example, number 6 is contained two times, 1 is not contained in C at all. 

Please, help Andrii to answer all the queries.

-----Input-----

The first line of the input contains two integers N and M. Each of the next M line contains one integer q, the query asked by Andrii.

-----Output-----
Output the answer for each query in separate lines as in example.

-----Constraints-----
- 1 ≤ N ≤ 109
- 1 ≤ M ≤ 105
- 1 ≤ q ≤ 3N

-----Example-----
Input:
3 5

The Bubble Cup hypothesis stood unsolved for $130$ years. Who ever proves the hypothesis will be regarded as one of the greatest mathematicians of our time! A famous mathematician Jerry Mao managed to reduce the hypothesis to this problem:

Given a number $m$, how many polynomials $P$ with coefficients in set ${\{0,1,2,3,4,5,6,7\}}$ have: $P(2)=m$?

Help Jerry Mao solve the long standing problem!


-----Input-----

The first line contains a single integer $t$ $(1 \leq t \leq 5\cdot 10^5)$ - number of test cases.

On next line there are $t$ numbers, $m_i$ $(1 \leq m_i \leq 10^{18})$ - meaning that in case $i$ you should solve for number $m_i$.


-----Output-----

For each test case $i$, print the answer on separate lines: number of polynomials $P$ as described in statement such that $P(2)=m_i$, modulo $10^9 + 7$.


-----Example-----
Input
2
2 4

Output
2
4



-----Note-----

In first case, for $m=2$, polynomials that satisfy the constraint are $x$ and $2$.

In second case, for $m=4$, polynomials that satisfy the constraint are $x^2$, $x + 2$, $2x$ and $4$.

There is a big staircase with $N$ steps (numbered $1$ through $N$) in ChefLand. Let's denote the height of the top of step $i$ by $h_i$. Chef Ada is currently under the staircase at height $0$ and she wants to reach the top of the staircase (the top of the last step). However, she can only jump from height $h_i$ to the top of a step at height $h_f$ if $h_f-h_i \le K$. To help Ada, we are going to construct some intermediate steps; each of them may be constructed between any two steps, or before the first step, and have any height. What is the minimum number of steps that need to be added to the staircase so that Ada could reach the top?

-----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 line of each test case contains two space-separated integers $N$ and $K$.
- The second line contains $N$ space-seperated integers $h_1, h_2, \dots, h_N$.

-----Output-----
For each test case, print a single line containing one integer — the minimum required number of steps.

-----Constraints-----
- $1 \le T \le 64$
- $1 \le N \le 128$
- $1 \le K \le 1,024$
- $1 \le h_i \le 1,024$ for each valid $i$

There are N towns on a line running east-west.
The towns are numbered 1 through N, in order from west to east.
Each point on the line has a one-dimensional coordinate, and a point that is farther east has a greater coordinate value.
The coordinate of town i is X_i.
You are now at town 1, and you want to visit all the other towns.
You have two ways to travel:
 - Walk on the line.
Your fatigue level increases by A each time you travel a distance of 1, regardless of direction.
 - Teleport to any location of your choice.
Your fatigue level increases by B, regardless of the distance covered.
Find the minimum possible total increase of your fatigue level when you visit all the towns in these two ways.

-----Constraints-----
 - All input values are integers.
 - 2≤N≤10^5
 - 1≤X_i≤10^9
 - For all i(1≤i≤N-1), X_i<X_{i+1}.
 - 1≤A≤10^9
 - 1≤B≤10^9

-----Input-----
The input is given from Standard Input in the following format:
N A B
X_1 X_2 ... X_N

-----Output-----
Print the minimum possible total increase of your fatigue level when you visit all the towns.

-----Sample Input-----
4 2 5
1 2 5 7

-----Sample Output-----
11

From town 1, walk a distance of 1 to town 2, then teleport to town 3, then walk a distance of 2 to town 4.
The total increase of your fatigue level in this case is 2×1+5+2×2=11, which is the minimum possible value.

Raj loves to listen to songs in his free time. It’s his birthday tomorrow and his friend Neelansh wants his gift to be the most unique. Being great at making music, he decides to produce a song for him. However, Raj likes songs according to their beauty. He determines the beauty of the song as the number of times all the octave musical tones are completed in ascending order.

He begins with a jumbled tone of length N and numbers each octave tone as 1,2,3….8.

Neelansh wants to maximize the beauty of the song but since he uses the trial version of the software,
- He cannot change the size of N.
- He cannot introduce any new tone, but can choose any two tones and swap their positions

However, Neelansh just received a mail that he needs to submit all his pending assignments by tomorrow. He has tons of assignments left to do, but he doesn’t want to spoil the idea of his gift. Can you help him? 

-----INPUT-----
- The first line contains a single integer T- the number of test cases  
- The first line of each test case contains a single integer N- the length of the song  
- The second line contains N- space separated integers ai,  ai+1,.....aN 

-----OUTPUT-----
For each test case, print a single line containing one integer- the maximum possible beauty of the song

You are fishing with polar bears Alice and Bob. While waiting for the fish to bite, the polar bears get bored. They come up with a game. First Alice and Bob each writes a 01-string (strings that only contain character "0" and "1") a and b. Then you try to turn a into b using two types of operations:  Write parity(a) to the end of a. For example, $1010 \rightarrow 10100$.  Remove the first character of a. For example, $1001 \rightarrow 001$. You cannot perform this operation if a is empty. 

You can use as many operations as you want. The problem is, is it possible to turn a into b?

The parity of a 01-string is 1 if there is an odd number of "1"s in the string, and 0 otherwise.


-----Input-----

The first line contains the string a and the second line contains the string b (1 ≤ |a|, |b| ≤ 1000). Both strings contain only the characters "0" and "1". Here |x| denotes the length of the string x.


-----Output-----

Print "YES" (without quotes) if it is possible to turn a into b, and "NO" (without quotes) otherwise.


-----Examples-----
Input
01011
0110

Output
YES

Input
0011
1110

Output
NO



-----Note-----

In the first sample, the steps are as follows: 01011 → 1011 → 011 → 0110

## Debugging sayHello function

The starship Enterprise has run into some problem when creating a program to greet everyone as they come aboard. It is your job to fix the code and get the program working again!
