SPOJ24（Small factorials）
24. Small factorialsProblem code: FCTRL2 |
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
