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 * $1 ≤ N ≤ 10^{5}$ ## Input The input is given from Standard Input in the following format: $N$ [samples]
