Write a program whose inputs are four integers, and whose outputs are the maximum and the minimum of the four values.

Ex: If the input is:

$121849$

the output is:

Maximum is $18$

Minimum is $4$

The program must define and call the following two functions. Define a function named MaxNumber that takes four integer parameters and returns an integer representing the maximum of the four integers. Define a function named MinNumber that takes four integer parameters and returns an integer representing the minimum of the four integers.

int MaxNumber$($int num$1,$ int num$2,$ int num$3,$ int num$4)$

int MinNumber$($int num$1,$ int num$2,$ int num$3,$ int num$4)$
