Extra Long Factorials

  • GabeKagan + 4 comments

    This is hilariously trivial in Ruby, which automatically creates big integers (Bignum) as needed. I should probably try it in a language that doesn't one of these days.

      I know. Try it in c, c++

      Python as well. Sum = n = input. while n > 1, decrement n and sum *= n, print sum, 5 lines.

      I think you're right, this is almost cheating in these languages.

            import math print math.factorial(n)

        def printfactorial(n):
    ausgabe = n
    for q in range(1, n):
        ausgabe *= (n - q)
    return print(ausgabe)

          Thanks a Lot.......I got cleared.

        print reduce(lambda x,y: x*y,xrange(2,long(raw_input().strip())+1))

      Another reason why I love (and sometimes hate) so much Ruby =]

      Yeah, I did that in Python first, wrote two lines of code. Felt like cheating, haha.
