What is the Fizz buzz test?

The Fizz buzz test is a simple coding challenge often used during the hiring process for software developers. It involves writing a short program that prints the numbers from 1 to 100, but for multiples of 3 prints "Fizz" instead of the number, and for multiples of 5 prints "Buzz". If the number is a multiple of both 3 and 5, the program should print "FizzBuzz".

This test is used to evaluate a candidate's familiarity with basic programming concepts and tasks, such as looping and conditionals. Despite its simplicity, it can be surprisingly effective in filtering out candidates who may struggle with even the most fundamental aspects of coding 1 .
