Priya loves bitwise AND, but she hates programming. Help her solve this problem.

Given an array $A$ of size $N$, let $B_{ij}$ denote the [bitwise AND] of $A[i]$ and $A[j]$. You have to find the number of pairs $(i, j)$, such that $i < j$ and $B_{ij} = A[i]$.

------ Input: ------
The first line of the input contains a single integer $T$ denoting the number of test cases.
The first line of each test case consists of a single integer $N$, denoting the Size of Array $A$.
The second line of each test case contains $N$ space-separated integers $A_{1}, A_{2}, A_{3} ... A_{N}$.

------ Output: ------
For each test case, output a single line, count of such pairs.

------ Constraints ------
$1 ≤ T ≤ 100$
$1 ≤ N ≤ 100$
$1 ≤ A[i] ≤ 100$

----- Sample Input 1 ------

----- explanation 1 ------
Example case 1: Number of valid pairs are -$(1,2),(1,3),(1,4),(1,5),(2,3),(2,4),(2,5),(3,4),(3,5)$ and $(4,5)$. Therefore, total valid pairs $= 10$.

Example case 2: Since $N=1$, therefore there are no valid pairs.
