Given an array and two integers say, **x **and **y**, find the number of sub-arrays in which the number of occurrences of **x** is equal to number of occurrences of **y**.

Input : arr[] = {1, 2, 1},
x = 1, y = 2
Output : 2
The possible sub-arrays have same equal number
of occurrences of x and y are:
1) {1, 2}, x and y have same occurrence(1).
2) {2, 1}, x and y have same occurrence(1).

**Input:**

The first line consists of an integer **T** i.e number of test cases. The first line of each test case consists of three integers **N**,**x** and **y**.The next line consists of **N** spaced integers.

**Output:**

Print the count of total number of sub-arrays satisfying specified condition.

**Constraints: **

1<=T<=100

1<=N,a[i],x,y<=100

**Example:**

Input:

2

3 1 2

1 2 1

3 4 6

1 2 1

**Output:**

2

6
