Have you heard of Fizz Buzz? It’s commonly used as an basic software interview question or an intro programming example. It’s based on a game meant to teach children division and goes like this. The children sit in a circle and count up from one; but, if your number is divisible by 3 you say “Fizz” instead of your number and if your number is divisible by 5 you say “Buzz” instead of your number. If your number is divisible by both 3 and 5 you say “Fizz Buzz”.
