Smallest Of Three Function

Write the body of min_of_three(first: int, second: int, third: int) -> int so it returns the smallest of its three parameters without using the built-in min: start by assuming the first is the smallest, then let each of the others replace it when it is smaller. The driver reads three integers and prints what the function returns; leave it as it is. Input: three lines, each an integer, no prompts.
