Small Factorial

You are asked to calculate factorials of some small positive integers.
Input


An integer t, 1<=t<=100, denoting the number of testcases, followed by t lines, each containing a single integer n, 1<=n<=100.
Output


For each integer n given at input, display a line with the value of n!

Example
Sample input:
4
1
2
5
3


Sample output:
1
2
120
6
