$5\mathrm{.}11$ LAB: User$-$Defined Functions: Max and min numbers

Define a function named LargestNumber that takes three integers as parameters and returns the largest integer. Define a second function named SmallestNumber that takes three integers as parameters and returns the smallest integer. Then, write a main program that reads three integers as inputs, calls functions LargestNumber$()$ and SmallestNumber$()$ with the inputs as arguments, and outputs the largest and the smallest of the three input values.

Ex: If the input is:

$\backslash (7\backslash$quad $15\backslash$quad $3\backslash )$

the output is:

$```$

largest: $15$

smallest: $3$

$```$

Your program should define and call two functions:

Function LargestNumber$($integer num$1,$ integer num$2,$ integer num$3)$ returns integer largestNum

Function SmallestNumber$($integer num$1,$ integer num$2,$ integer num$3)$ returns integer smallestNum
