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.
N = int(input())
ans = 1
for i in range(1, N+1):
  ans * i
print(ans)

MOD = int(1e9)+7
N = int(input())
ans = 1
for i in range(1, N+1):
  ans *= i
  ans %= MOD
print(ans)
