Given an array A[] of n integers, the task is to find the number of subarrays whose minimal and maximum elements are same.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of two lines. First line of each test case contains an integer N and the second line contains N space separated array elements.

Output:
For each test case, print the count of required subarrays in new line.

Constraints:
1 <= T <= 100
1 <= N <= 105

1 <= A[i] <= 105
