Given an array of positive integers and two positive integers K1 and K2. Find sum of all elements greater tha K1th and smaller than K2th smallest elements of array.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case contains an integer N, denoting the length of the array. Next line contains N space seperated integers of the array. Third line contains two space seperated integers denoting K1th and K2th smallest elements.

Output:
For each test case, output the sum of all the elements between K1th and K2th smallest elements.

Constraints:
1 <= T <= 100
1 <= N <= 107
1 <= K1, K2 <= 1014

Example:
Input

2

20 8 22 4 12 10 14
3 6
6

10 2 50 12 48 13
2 6

Output:
26
73

Explanation:
Test Case 1:
3rd smallest element is 10
6th smallest element is 20
Sum of all element between K1 & K2 is 12 + 14 = 26
