'{{short description|Group word game to teach mathematical division}} {{More citations needed|date=May 2023|talk=Sources needed}} '''Fizz buzz''' is a group word game for children to teach them about [[division (mathematics)|division]].<ref>{{cite book |last=Rees |first=Janet |title=Fizz Buzz: 101 Spoken Numeracy Games – Ideal for Mental Maths |date=2002 |publisher=Learning Development Aids |isbn=978-1855033528 }}</ref> Players take turns to count incrementally, replacing any number divisible by three with the word "fizz", and any number divisible by five with the word "buzz", and any number divisible by both 3 and 5 with the word "fizzbuzz". == Implementations == • Java public void fizzBuzz(int n) { if(n <= 0) { return -1; } for(int i = 0: i <= n; i++) { if(i % 3 == 0 && i % 5 == 0) { System.out.println("FizzBuzz"); } else if(i % 3 == 0) { System.out.println("Fizz"); } else if(i % 5 == 0) { System.out.println("Buzz"); } } }   == Play == Players generally sit in a circle. The player designated to go first says the number "1", and the players then count upwards in turn. However, any number [[division (mathematics)|divisible]] by three is replaced by the word ''fizz'' and any number divisible by five by the word ''buzz''. Numbers divisible by both three and five (i.e. divisible by 15) become ''fizz buzz''. A player who hesitates or makes a mistake is eliminated. For example, a typical round of fizz buzz would start as follows: {{blockquote|1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz, 11, Fizz, 13, 14, Fizz Buzz, 16, 17, Fizz, 19, Buzz, Fizz, 22, 23, Fizz, Buzz, 26, Fizz, 28, 29, Fizz Buzz, 31, 32, Fizz, 34, Buzz, Fizz, ...}} == Other variations == In some versions of the game, other divisibility rules such as 7 can be used instead. Another rule that may be used to complicate the game is where numbers containing a digit also trigger the corresponding rule (for instance, 52 would use the same rule for a number divisible by 5). == Programming == Fizz buzz (often spelled '''FizzBuzz''' in this context) has been used as an interview screening device for [[computer programmers]]. Writing a [[computer program|program]] to output the first 100 FizzBuzz numbers is a relatively trivial problem requiring little more than a loop and conditional statements. However, its value in coding interviews is to analyze fundamental coding habits that may be indicative of overall coding ingenuity. == References == <references /> == External links == * [https://web.archive.org/web/20160805202854/http://cocktails.about.com/od/partiesholidays/p/biz_buz_gm.htm About.com: Bizz Buzz- The Drinking Thinking Game] * [https://rosettacode.org/wiki/FizzBuzz Rosetta Code: Fizz Buzz at Rosetta Code] * [http://philcrissman.net/posts/eulers-fizzbuzz/ Euler's FizzBuzz], an unorthodox programmatic solution making use of [[Euler's theorem]] * [https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpriseEdition Enterprise FizzBuzz], Comical 'enterprise' implementation of FizzBuzz with intentional verbosity [[Category:Car games]] [[Category:Children's games]] [[Category:Drinking games]] [[Category:Mathematical games]] [[Category:Division (mathematics)]]'
