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
