### How do you find the factorial of an array?

The recursive formulae to calculate the factorial of a number is: fact(N) = N*fact(N-1). Hence, we will build an array in a bottom-up manner using the above recursion. Once we have stored the values in the array then we can answer the queries in O(1) time.

How does a factorial program work?

Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example factorial of 6 is 6*5*4*3*2*1 which is 720.

What is factorial programming?

C++ProgrammingServer Side Programming. Factorial of a non-negative integer n is the product of all the positive integers that are less than or equal to n. For example: The factorial of 5 is 120.

### How to calculate factorial of a number in Python?

From the below program, the Factorial of a number is calculated using a function called fact with a return type of integer. 1. First the main function will be called for execution. 2. fact function will be called from main function to run the code. 3. the fact function will execute and return final fact value and print from main function

What is factorial in math?

Factorial of any positive integer ‘n’ is a product of all the whole numbers from 1 to n (both included). In Mathematics, an exclamation sign is used to represent the factorial of a number.

How to calculate factorial of a non-negative integer?

Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example factorial of 6 is 6*5*4*3*2*1 which is 720. Recursive Solution: Factorial can be calculated using following recursive formula. n! = n * (n-1)! n! = 1 if n = 0 or n = 1.
