Problem Statement
Snuke loves working out. He is now exercising $N$ times.
Before he starts exercising, his power is $1$. After he exercises for the $i$-th time, his power gets multiplied by $i$.
Find Snuke's power after he exercises $N$ times. Since the answer can be extremely large, print the answer modulo $10^{9}+7$.
Constraints
