Given an array of n integers and q queries. Write a program to print floor value of mean in range l to r for each query in a new line.

Examples:
Input : arr[] = {1, 2, 3, 4, 5}
        q = 3
        0 2
        1 3
        0 4
Output : 2
         3
         3
Here for 0 to 2 (1 + 2 + 3) / 3 = 2

Input : arr[] = {6, 7, 8, 10}
        q = 2
        0 3
        1 2
Output : 7
         7

Input:
The first line consists of an integer T i.e number of test cases. The first line of each test case consists of two integer n and q.The next line consists of n spaced integers. The next line consists of 2*q spaced integers each pair representing the range.

Output:
Print the mean(floor value) in given range for each query in new line.

Constraints: 
1<=T<=100
1<=q 1<=a[i]<=1000

Example:
Input:

1
5 3
1 2 3 4 5
0 2 1 3 0 4

Output:
2 3 3
