Given an array A[] of n elements. Your task is to complete the Function num which returns an integer denotingthe total number of times digit k appears in the whole array.

For Example:

A[]={11,12,13,14,15}, k=1

Output=6 //Count of the digit 1 in the array

Input: The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. The first line of each test case contain an integer n denoting the size of the array A[]. Then in the second line are n space separated values of the array A[] .In the third line of each test case contains an integer k, which is the digit to be counted.

Output: For each test case in a new line print the number of elements counted.

Constraints:
1<=T<=100
1<=n<=20
1<=A[]<=1000

Example(To be used for expected output):
Input:
2
5
11 12 13 14 15
1
4
0 10 20 30
