Given a positive integer N, you should output the most right digit of N^N.
The input contains several test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow.
Each test case contains a single positive integer N(1<=N<=1,000,000,000).
For each test case, you should output the rightmost digit of N^N.
