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())
power = 1
for i in range(N):
  power = power*i%(10**9+7)
  
print(power)
N = int(input())
power = 1
for i in range(N):
  power = power*(i+1) % (10**9+7)
  
print(power)
