TFB stands for "The Fizz Buzz". It is a classic computer programming exercise used to evaluate a candidate's basic programming skills, particularly in the early stages of technical interviews. The Fizz Buzz problem involves writing a program that prints out numbers from 1 to a given upper limit, but with a few specific conditions.
In the Fizz Buzz sequence, numbers that are divisible by 3 are replaced with the word "Fizz," numbers divisible by 5 are replaced with the word "Buzz," and numbers divisible by both 3 and 5 (15, for example), are replaced with "FizzBuzz." The output should be a series of numbers and words in the correct order.
As an example, if the upper limit is defined as 20, the program should output: "1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz, 11, Fizz, 13, 14, FizzBuzz, 16, 17, Fizz, 19, Buzz."
The Fizz Buzz problem originated as a simple exercise to test a candidate's ability to construct an if-else program logic. However, it has gained popularity as a way to gauge the fundamental understanding of programming concepts like loops and conditionals. It also serves as a test of problem-solving ability and attention to detail.
