Description:
      给你一个N，你应该输出N^N最左边一位。
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:
对于每组测试数据，你应该输出N^N最左边一位。
Sample Input:
234
Sample Output:
22
Hint:
对于3 * 3 * 3 = 27,最左边一位是2. 对于4 * 4 * 4 * 4 = 256, 最左边一位是2.
