Factorial of a Number Send Feedback You are given an integer ‘N’. You have to print the value of Factorial of ‘N’. The Factorial of a number ‘N’ is defined as the product of all numbers from 1 to ‘N’. For Example: Consider if ‘N’ = 4, the Factorial of 4 will be the product of all numbers from 1 to 4, which is 1 * 2 * 3 * 4 = 24. Hence, the answer is 24. Input Format: The test case contains one single integer ‘N’ representing the given integer. Output Format: Print the value of the factorial of ‘N’.

Sure, here is a step-by-step guide on how to calculate the factorial of a number:

1. First, understand what a factorial is. The factorial of a number 'N' is the product of all positive integers less than or equal to 'N'. It is denoted by 'N!'. For example, the factorial of 4 (denoted as 4!) is 123*4 = 24.

2. Now, to calculate the factorial of a number, start by initializing a variable to 1. This variable will hold the result of the factorial calculation.

3. Next, create a loop that starts from 1 and goes up to the number 'N'.

4. In each iteration of the loop, multiply the result variable with the current number.

5. Continue this process until you have multiplied the result variable by every number up to 'N'.

6. Finally, the value of the result variable will be the factorial of 'N'.

Here is a simple Python code that implements the above steps:

def factorial(N):
    result = 1
    for i in range(1, N+1):
        result *= i
    return result

N = 4
print(factorial(N))  # Output: 24

This code defines a function called 'factorial' that calculates the factorial of a given number 'N'. It then calls this function with 'N' = 4 and prints the result.
