Given an array of n integers, the task is to find the number of subarrays whose minimal and maximum elements are same.
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.
For each test case, print the count of required subarrays in new line.
1 2 3 4
1 1 3
Input: 1 1 3 Output: 4 Explanation: The subarrays are (1), (1), (3) and (1, 1)
