Problem$-4$ Write a python code that takes an integer from a keyboard $($denoted by variable $x).$ If the number is less than $99$ and odd, your program calculates its factorial $(x!)$ and prints the factorial value in your screen. If the number is less than $99$ and is even, your program prints, "this is an even number". If the number is greater than $99,$ it prints "the number is too big".
