Difficulty: EASY

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

Input
An integer T, denoting the number of testcases, followed by T
lines, each containing a single integer N.

Output 
For each integer N given at input, output a single line the value of N!

Input Constraint

1 ≤ T ≤ 100

1 ≤ N ≤ 100
