Milly is playing with an array A of size N. She is trying to find those non-empty subarrays (sequence of consecutive elements) whose maximum and minimum values are identical. Milly got confused while counting. Your task is to help her in this problem.

Input

  • First line of the input will contain T denoting the number of test-cases.
  • For every test case, first line will contain N. Next line will contain N space separated integers denoting Ai.

Output

  • For every test case, print the required answer in a separate line.

Constraints

  • 1 ≤ T ≤ 10
  • 1 ≤ N ≤ 105
  • 1 ≤ |Ai| ≤ 109
  • Here, || denotes the absolute value.
