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$0$ and SmallestNumber$0$ with the inputs as arguments, and outputs the largest and the smallest of the three input values.

Ex: If the input is:

$715,3$

the output is:

largest: $15$

smallest: $3$
