Factorial of a given number

Title: Factorial of a given number

n!=n*(n-1)*(n-2)*…..3,2,1

5!=5*(5-1)*(5-2)*(5-3)*(5-4)

5!=5*4*3*2*1

5!=120

Program-1:

n=int(input("Enter n value\n"))

f=1

for i in range(n,0,-1):

    f=f*i

print("The factorial of ",n," is ",f)

Output:

            Enter n value

5

The factorial of  5  is  120

Program-2:

n=int(input("Enter n value\n"))

f=1

for i in range(1,n+1):

    f=f*i

print("The factorial of ",n," is ",f)

Output:

            Enter n value

5

The factorial of  5  is  120
