When factorial(0) is called, what is the output?

Factorial Function

The factorial function calculates the product of all positive integers less than or equal to a given number.
factorial(6) returns 720.
factorial(4) returns 24.
factorial(0) returns 1.

Armstrong Number

An Armstrong number is a number that is equal to the sum of its own digits, each raised to the power of the number of digits.
The function is_armstrong checks if a number is an Armstrong number.
153, 371, and 9474 are Armstrong numbers.
123 is not an Armstrong number.

Minimum and Maximum Values

The min function returns the minimum value in a set of numbers.
The max function returns the maximum value in a set of numbers.
In the set of numbers {5, 2, 9, 1, 7}, the minimum value is 1 and the maximum value is 9.

Prime Number

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
The function Find_Prime_No checks if a number is prime.
13 is a prime number.
The Find_Prime_No function uses a loop to check if a number is divisible by any number from 2 to n-1, where n is the input number. If it is not divisible, it returns TRUE, indicating that the number is prime.
