You are given an array A of size N. You need to print elements of A in alternate order.

Input Format:
The first line of input contains T denoting the number of testcases. T testcases follow. Each test case contains two lines of input. The first line contains N and the second line contains the elements of the array.

Output Format:
For each testcase,
print the alternate elements of the array(starting from index 0).

Your Task:
Since this is a function problem, you just need to complete the provided function void print(int ar[],int n)

Constraints:

1 <= N <= 105
1 <= Ai <= 105

Example:
