Constraints
1 < = N < = 500

see the constraints they are very large for factorial

100 factorial has 158 digits
you can’t store them in int ,float or double etc

you have to use array for this

For complete Algorithm see this

Doubt doubt doubt

he following is a detailed algorithm for finding factorial. factorial(n) Create an array ‘res[]’ of MAX size where MAX is number of maximum digits in output. Initialize value stored in ‘res[]’ as 1 and initialize ‘res_size’ (size of ‘res[]’) as 1. Do following for all numbers from x = 2 to n. ……a) Multiply x with res[] and update res[] and res_size to store the multiplication result. How to multiply a number ‘x’ with the number stored in res[]? The idea is to use simple school mathematics.…
