Extra Long Factorials
Extra Long Factorials You are given an integer N . Print the factorial of this number. N ! = N × ( N − 1 ) × ( N − 2 ) × ⋯ × 3 × 2 × 1 Input Input consists of a single integer N , where 1 ≤ N ≤ 100 Output Print the factorial of N . Example For an input of 25 , you would print 15511210043330985984000000 . Note: Factorials of N > 20 can't be stored even in a 64 − b i t long long variable. Big integers must be used for such calculations. Languages like Java, Python, Ruby etc. can handle big integers but we need to write additional code in C/C++ to handle huge values. We recommend solving this challenge using BigIntegers. or by using python---- from math import factorial n=int(raw_input()) print factorial(n)
