The code is structured in multiple functions.

Heyo (or FizzBop)

This assignment is a combination of previous assignments using a loop to iterate over user inputted numbers (examine getVaules function.) to then generate an array (examine generateNumbers) and then displays them with a bit of a twist: numbers divisible by 3 and 5 are highlighted as HEYO (or fizzbop) numbers divisible by five are yo and numbers divisible by three are hey. The part that gave me the most trouble was the if statements in displayNumbers, I had them backwards at first with it being "divisible by 3, 5, or 3 & 5" but as you can see it should be 3 & 5 and if not then 5 then 3. The very last if statement took a bit of testing but it fixes the formatting as it was printing singular rows, with this addition it can print 4 table columns per row!
