from math import factorial

print(factorial(int(input())))

2)

f1 = f2 = 1

n = int(input())

print(f1, f2, end=' ')

for i in range(2, n):

   f1, f2 = f2, f1 + f2

   print(f2, end=' ')

3)

j = int(input())

summ = 0

for n in range(2, j + 1):

   if n > 1:

       for i in range(2, n):

               if (n % i) == 0:

                   break

       else:

           summ += n

print(summ)
