Problem Description
Given a positive integer N, you should output the most right digit of N^N.
|
Input
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).
|
Output
For each test case, you should output the rightmost digit of N^N.
|
Sample Input
2 3 4 |
Sample Output
7 6 Hint
In the first case, 3 * 3 * 3 = 27, so the rightmost digit is 7. In the second case, 4 * 4 * 4 * 4 = 256, so the rightmost digit is 6. |
