You are given a sequence $A_1, A_2, \ldots, A_N$. You want all the elements of the sequence to be equal. In order to achieve that, you may perform zero or more moves. In each move, you must choose an index $i$ ($1 \le i \le N$), then choose $j = i-1$ or $j = i+1$ (it is not allowed to choose $j = 0$ or $j = N+1$) and change the value of $A_i$ to $A_j$ — in other words, you should replace the value of one element of the sequence by one of its adjacent elements.
What is the minimum number of moves you need to make in order to make all the elements of the sequence equal?

-----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 $A_1, A_2, \ldots, A_N$.

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

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

-----Example Input-----
3
5
1 1 1 1 1
4
9 8 1 8
2
1 9

-----Example Output-----
0
2
1

-----Explanation-----
Example case 1: No moves are needed since all the elements are already equal.
Example case 3: We can perform one move on either $A_1$ or $A_2$.

There are $X$ people participating in a quiz competition and their IDs have been numbered from $1$ to $X$ (both inclusive). Beth needs to form a team among these $X$ participants. She has been given an integer $Y$. She can choose participants whose ID numbers are divisible by $Y$. 
Now that the team is formed, Beth wants to know the strength of her team. The strength of a team is the sum of all the last digits of the team members’ ID numbers.
Can you help Beth in finding the strength of her team?

-----Input:-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. $T$ lines follow 
- The first line of each test case contains $X$ and $Y$. 

-----Output:-----
- For each test case print the strength of Beth's team

-----Constraints-----
- $1 \leq T \leq 1000$
- $1 \leq X,Y \leq 10^{20}$

-----Sample Input:-----
2
10 3

15 5

-----Sample Output:-----
18 

10

-----EXPLANATION:-----
- Example case 1: ID numbers divisible by 3 are 3,6,9 and the sum of the last digits are 3+6+9=18

You are given a prime number $p$, $n$ integers $a_1, a_2, \ldots, a_n$, and an integer $k$. 

Find the number of pairs of indexes $(i, j)$ ($1 \le i < j \le n$) for which $(a_i + a_j)(a_i^2 + a_j^2) \equiv k \bmod p$.


-----Input-----

The first line contains integers $n, p, k$ ($2 \le n \le 3 \cdot 10^5$, $2 \le p \le 10^9$, $0 \le k \le p-1$). $p$ is guaranteed to be prime.

The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ($0 \le a_i \le p-1$). It is guaranteed that all elements are different.


-----Output-----

Output a single integer — answer to the problem.


-----Examples-----
Input
3 3 0
0 1 2

Output
1
Input
6 7 2
1 2 3 4 5 6

Output
3


-----Note-----

In the first example:

$(0+1)(0^2 + 1^2) = 1 \equiv 1 \bmod 3$.

$(0+2)(0^2 + 2^2) = 8 \equiv 2 \bmod 3$.

$(1+2)(1^2 + 2^2) = 15 \equiv 0 \bmod 3$.

So only $1$ pair satisfies the condition.

In the second example, there are $3$ such pairs: $(1, 5)$, $(2, 3)$, $(4, 6)$.

Little Petya likes points a lot. Recently his mom has presented him n points lying on the line OX. Now Petya is wondering in how many ways he can choose three distinct points so that the distance between the two farthest of them doesn't exceed d.

Note that the order of the points inside the group of three chosen points doesn't matter.


-----Input-----

The first line contains two integers: n and d (1 ≤ n ≤ 10^5; 1 ≤ d ≤ 10^9). The next line contains n integers x_1, x_2, ..., x_{n}, their absolute value doesn't exceed 10^9 — the x-coordinates of the points that Petya has got.

It is guaranteed that the coordinates of the points in the input strictly increase.


-----Output-----

Print a single integer — the number of groups of three points, where the distance between two farthest points doesn't exceed d.

Please do not use the %lld specifier to read or write 64-bit integers in С++. It is preferred to use the cin, cout streams or the %I64d specifier.


-----Examples-----
Input
4 3
1 2 3 4

Output
4

Input
4 2
-3 -2 -1 0

Output
2

Input
5 19
1 10 20 30 50

Output
1



-----Note-----

In the first sample any group of three points meets our conditions.

In the seconds sample only 2 groups of three points meet our conditions: {-3, -2, -1} and {-2, -1, 0}.

In the third sample only one group does: {1, 10, 20}.

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 $i$
- $h_i < h_{i+1}$ for each valid $i$

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.

Chef has been working in a restaurant which has  N  floors. He wants to minimize the time it takes him to go from the N-th floor to ground floor. He can either take the elevator or the stairs. 
The stairs are at an angle of 45 degrees and Chef's velocity is V1 m/s when taking the stairs down. The elevator on the other hand moves with a velocity V2 m/s. Whenever an elevator is called, it always starts from ground floor and goes to N-th floor where it collects Chef (collecting takes no time), it then makes its way down to the ground floor with Chef in it.  

The elevator cross a total distance equal to N meters when going from N-th floor to ground floor or vice versa, while the length of the stairs is sqrt(2) * N because the stairs is at angle 45 degrees.

Chef has enlisted your help to decide whether he should use stairs or the elevator to minimize his travel time. Can you help him out?

-----Input-----
The first line contains a single integer T, the number of test cases. Each test case is described by a single line containing three space-separated integers N, V1, V2. 

-----Output-----
For each test case, output a single line with string Elevator or Stairs, denoting the answer to the problem.

-----Constraints-----
- 1 ≤ T ≤  1000 
- 1 ≤ N, V1, V2 ≤  100 

-----Example-----

"I don't have any fancy quotes." - vijju123
Chef was reading some quotes by great people. Now, he is interested in classifying all the fancy quotes he knows. He thinks that all fancy quotes which contain the word "not" are Real Fancy; quotes that do not contain it are regularly fancy.
You are given some quotes. For each quote, you need to tell Chef if it is Real Fancy or just regularly fancy.

-----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 a single string $S$ denoting a quote.

-----Output-----
For each test case, print a single line containing the string "Real Fancy" or "regularly fancy" (without quotes).

-----Constraints-----
- $1 \le T \le 50$
- $1 \le |S| \le 100$
- each character of $S$ is either a lowercase English letter or a space

-----Subtasks-----
Subtask #1 (100 points): original constraints

-----Example Input-----
2
i do not have any fancy quotes
when nothing goes right go left

-----Example Output-----
Real Fancy
regularly fancy

-----Explanation-----
Example case 1: "i do not have any fancy quotes"
Example case 2: The word "not" does not appear in the given quote.

Soma is a fashionable girl. She absolutely loves shiny stones that she can put on as jewellery accessories. She has been collecting stones since her childhood - now she has become really good with identifying which ones are fake and which ones are not.  Her King requested for her help in mining precious stones, so she has told him which all stones are jewels and which are not. Given her description, your task is  to count the number of jewel stones. 

More formally, you're given a string J composed of latin characters where each character is a jewel. You're also given a string S composed of latin characters where each character is a mined stone. You have to find out how many characters of S are in J as well. 

-----Input-----

First line contains an integer T denoting the number of test cases. Then follow T test cases. Each test case consists of two lines, each of which contains a string composed of English lower case and upper characters. First of these is the jewel string J and the second one is stone string S. 
You can assume that  1 <= T <= 100, 1 <= |J|, |S| <= 100


-----Output-----
Output for each test case, a single integer, the number of jewels mined. 

-----Example-----
Input:

Dexter, being irritated by DD, gave her a lucrative game to play to keep her busy.
There are $N$ bags numbered $1$ to $N$. The $i_{th}$ bag contains $A_i$ coins. The bags are placed in a circular order such that the $N_{th}$ bag is adjacent to the $1^{st}$ bag. 
DD can select $K$ consecutive adjacent bags and take all the coins in them.   Help her find the maximum number of coins she can take by making the ideal choice.
Note that the selected bags must be consecutive. Since they are placed in circular order, bag number $1$ and $N$ are considered to be consecutive.

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- First-line contains $N$ and $K$.
- Second-line contains $N$ numbers $A_1, A_2,...,A_N$,  

-----Output:-----
For each test case, output in a single line, the maximum money that can be collected by DD.

-----Constraints-----
- $1 \leq T \leq 100$
- $5 \leq N \leq 10^5$
- $1 \leq K < N$
- $1 \leq A_i \leq 10^5$
Sum of $N$ over all test cases is less than $10^6$

-----Sample Input:-----
1
5 3
8 6 9 4 10

-----Sample Output:-----
24

-----EXPLANATION:-----
The ideal choice would be to take the last bag with $10$ coins and the first $2$ bags with $8$ and $6$ coins.

Tejas has invited the Clash Team for a Dinner Party. He places V empty plates (numbered from 1 to V inclusive) in a straight line on a table. He has prepared 2 kinds of Delicious Dishes named dish A and dish B.

He has exactly V servings of Dish A and W servings of dish B. 

Now he wants to serve the dishes in such a way that if theith plate has serving of Dish A then (i-1)th plate should not have serving of Dish B. Assuming all the Dishes are identical find number of ways Tejas can serve the Clash Team.

-----Input-----
- The first line of the input contains an integer T denoting the number of test cases . The description of T testcases follow.

- The first line of each test case contains two space seperated integers V W .

-----Output-----
For each test case, output the number of ways Tejas can serve the Clash Team.


-----Constraints-----

- 1 ≤ T ≤ 100
- 1 ≤ V ≤ 1000
- 1 ≤ W ≤ 1000

-----Example-----
Input:

1

3 3 

Output:
4



-----Explanation-----

In the above example the 4 ways are:

AAA

AAB

ABB

BBB
