Snackdown 2019 is coming! There are two rounds (round A and round B) after the qualification round. From both of them, teams can qualify to the pre-elimination round. According to the rules, in each of these two rounds, teams are sorted in descending order by their score and each team with a score greater or equal to the score of the team at the $K=1500$-th place advances to the pre-elimination round (this means it is possible to have more than $K$ qualified teams from each round in the case of one or more ties after the $K$-th place).
Today, the organizers ask you to count the number of teams which would qualify for the pre-elimination round from round A for a given value of $K$ (possibly different from $1500$). They provided the scores of all teams to you; you should ensure that all teams scoring at least as many points as the $K$-th team qualify.

-----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-separated integers $S_1, S_2, \dots, S_N$.

-----Output-----
For each test case, print a single line containing one integer — the number of qualified teams.

-----Constraints-----
- $1 \le T \le 1,000$
- $1 \le K \le N \le 10^5$
- $1 \le S_i \le 10^9$ for each valid $i$
- the sum of $N$ for all test cases does not exceed $10^6$

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

Given n words w[1..n], which originate from the same stem (e.g. grace, graceful, disgraceful, gracefully), we are interested in the original stem. To simplify the problem, we define the stem as the longest consecutive substring that occurs in all the n words. If there are ties, we will choose the smallest one in the alphabetical (lexicographic) order.

-----Input-----
The first line contains an integer T denoting the total number of test cases.
In each test cases, the first line contains an integer n denoting the number of words. In the second line, n words w[1..n] consisting of lower case characters are given as a single space-spearated list.

-----Output-----
For each test case, output the stem in a new line.

-----Constraints-----
- 1 <= T <= 10
- 1 <= n <= 10
- 1 <= |w[i]| <= 20

-----Example-----
Input:
1
4
grace graceful disgraceful gracefully
Output:
grace

-----Explanation-----
The stem is grace.

10^{10^{10}} participants, including Takahashi, competed in two programming contests.
In each contest, all participants had distinct ranks from first through 10^{10^{10}}-th.
The score of a participant is the product of his/her ranks in the two contests.
Process the following Q queries:
 - In the i-th query, you are given two positive integers A_i and B_i. Assuming that Takahashi was ranked A_i-th in the first contest and B_i-th in the second contest, find the maximum possible number of participants whose scores are smaller than Takahashi's.

-----Constraints-----
 - 1 \leq Q \leq 100
 - 1\leq A_i,B_i\leq 10^9(1\leq i\leq Q)
 - All values in input are integers.

-----Input-----
Input is given from Standard Input in the following format:
Q
A_1 B_1
:
A_Q B_Q

-----Output-----
For each query, print the maximum possible number of participants whose scores are smaller than Takahashi's.

-----Sample Input-----
8

10 5
3 3
4 11
8 9

Let us denote a participant who was ranked x-th in the first contest and y-th in the second contest as (x,y).
In the first query, (2,1) is a possible candidate of a participant whose score is smaller than Takahashi's. There are never two or more participants whose scores are smaller than Takahashi's, so we should print 1.

Today Chef wants to evaluate the dishes of his $N$ students. He asks each one to cook a dish and present it to him.
Chef loves his secret ingredient, and only likes dishes with at least $X$ grams of it.
Given $N$, $X$ and the amount of secret ingredient used by each student $A_i$, find out whether Chef will like at least one dish. 

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- The first line of each testcase contains two integers $N$ 
(number of students) and $X$ (minimum amount of secret ingredient that a dish must contain for Chef to like it).
- The next line contains $N$ space separated integers, $A_i$ denoting the amount of secret ingredient used by the students in their dishes.

-----Output:-----
For each testcase, print a single string "YES" if Chef likes at least one dish. Otherwise, print "NO". (Without quotes).

-----Constraints:-----
- $1 \leq T \leq 100$
- $1 \leq N \leq 1000$
- $1 \leq X \leq 1000000$
- $1 \leq A_i \leq 1000000$

Chefina  is  always interested to play with string. But due to exam pressure she has no time to solve a string problem. She wants your help. Can you help her to solve that problem?
You are given a string. You have to find out the $Wonder$ $Sum$ of the string. $Wonder$ $Sum$ of a string is defined as the sum of the value of each character of the string. 
The value of each character means:
- If the string is started with "a" , then the value of each character of the string is like "a"=100, "b"=101, "c"="102" ………"z"=125.
- If the string is started with "z" , then the value of each character of the string is like "a"=2600, "b"=2601, "c"="2602" ………"z"=2625.
Since even the $Wonder$ $Sum$ can be large, output $Wonder$ $Sum$ modulo  ($10^9 + 7$).

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, a string $S$ with lower case alphabet 
only.

-----Output:-----
For each testcase, output in a single line integer i.e.  $Wonder$ $Sum$ modulo  ($10^9 + 7$).

-----Constraints-----
- $1 \leq T \leq 1000$
- $1 \leq |S| \leq 10^5$

-----Sample Input:-----
$2$$cab$
$sdef$

-----Sample Output:-----
$903$
$7630$

-----EXPLANATION:-----
i) For the first test case, since the string is started with "$c$", so output is ($302$+$300$+$301$)=$903$
ii)For the second test case, since the string is started with "$s$", so output is ($1918$+$1903$+$1904$+$1905$)=$7630$

-----General Statement:-----
Read a number in scientific notation and output its equivalent decimal value.

-----Input:-----
All data is on a single line. The first integer indicates how many pairs of numbers follow. The first of each pair is A, the base number, and the second is E, the power of 10.

-----Output:-----
Round each answer to 2 decimal places. Trailing zeros to the right of the decimal point are required. A leading zero to the left of the decimal point is not required.
The output is to be formatted exactly like that for the sample output given below.

-----Assumptions:-----
E is in the range –10 .. 10. A is 1 or larger but less than 10.
Discussion: 
If A = 3.926 and E = 4, the number represented is 3.926 X 104 or 39260, which is 39260.00 when rounded to 2 decimal places.

-----Sample Input:-----
4 4.296 3 3.8 -2 1.8 2 2.8678 1

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

Chef has a sequence of positive integers $A_1, A_2, \ldots, A_N$. He wants to choose some elements of this sequence (possibly none or all of them) and compute their MEX, i.e. the smallest positive integer which does not occur among the chosen elements. For example, the MEX of $[1, 2, 4]$ is $3$.
Help Chef find the largest number of elements of the sequence $A$ which he can choose such that their MEX is equal to $M$, or determine that it is impossible.

-----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 $M$.
- 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 maximum number of elements Chef can choose, or $-1$ if he cannot choose elements in such a way that their MEX is $M$.

-----Constraints-----
- $1 \le T \le 100$
- $2 \le M \le N \le 10^5$
- $1 \le A_i \le 10^9$ for each valid $i$
- the sum of $N$ over all test cases does not exceed $10^6$

-----Example Input-----
1
3 3
1 2 4

-----Example Output-----
3

-----Explanation-----
Example case 1: The MEX of whole array is 3. Hence, we can choose all the elements.

In Programmers Army Land, people have started preparation as sports day is scheduled next week.
You are given a task to form 1 team of $k$ consecutive players, from a list of sports player whose powers are given to you.
You want your team to win this championship, so you have to chose your $k$ team players optimally i.e. there must not be any other $k$ consecutive team players who have their total power greater than your team members total power.

-----Input:-----
- The first line of the input contains a single integer $T$. $T$ denoting the number of test cases. The description of $T$ test cases is as follows.
- The next line of the input contains 2 space separated integers $N$ and $K$. $N$ denotes the total number of players and $K$ denotes the number of players allowed in a team.
- The next line of the input contains $N$ space-separated integers $A1, A2, A3...An$ where $ith$ number denotes power of $ith$ player.
Note: power of players can also be negative

-----Output:-----
- For each test-case print the total power that your selected team have(each test case output must be printed on a new line).

-----Constraints:-----
- $1 \leq T \leq 10^3$
- $1 \leq N,K \leq 10^5$
- $-10^7 \leq A1, A2, A3...An \leq 10^7$

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

-----Sample Output:-----
12

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.
