factorial() function from the NumPy library is actually a function from the maths library of python. It is similar to scipy.math.factorial(). The function computes the factorial of positive numbers. It does not work for input arrays. In order to calculate the factorial of an input array, c...

By definition, a factorial is the product of a positive integer and all the positive integers that are less than or equal to the given number. In other words, getting a factorial of a number means to multiply all whole numbers from that number, down to 1. 0! equals 1 as well, by co...

n can be from 0 to 10000. Time limit: 1 second. I think there was up to 100 numbers for each test set. My solution was pretty fast but not fast enough, so I just let it run for some time. It built an array of pre-calculated values which I could use in my code. It was a ...
