The problem is deceptively simple but you can't solve it if you don't know how to build programming logic.

FizzBuzz is one of the most famous programming questions from interviews, which is generally used to weed out programmers who can't program. The most efficient? we almost have a tie between the following 3 marked in yellow.Ĭomparing int values (in loop), using 4 (in loop) modulo operations and chained if.else: for (int i = 1 i 0 & b > 0) result += i.ToString() Ĭomparing strings, using 2 (in loop) modulo operations: for (int i = 1 i 0 ? messages : i.ToString()) + ', ' Īcc = acc > 2 | c < < Download the full C# codeįor more exploration, visit this discussion. Matt!Īs shown below, the most effective methods were the ones with: 1. Note that I’m using the + sign to concatenate the strings in my examples, yet a more efficient way in C# will be to use StringBuilder. I’m using C# in the implementation example, yet the above methods apply to all languages (possibly languages will deffer being better than others comparing ints vs. Count 3 and 5 down or up as i progress (testing counts of 3 and 5).It seems that there are 4 main patterns to solve the FizzBuzz problem: Which FizzBuzz solution is the most efficient? Then I added a simple timing and below are the results. So I’ve looked around the various suggestions (more than 80 languages!), and isolated the key ways to solve the problem. The FizzBuzz problem seems so naive and simple to solve, that it becomes an even more intriguing task to optimize it. It was also said that during an interview, solving the problem in more efficient less readable manner would disqualify the developer. Maybe because its original goal was to screen “bad” developers rather than actually solve the problem efficiently or demonstrate creativity.

This little “poor-developer filter” was discussed and solved many times.ĭespite the number of discussions it spur, and the many suggested ways to solve the problem, the question regarding which solution would be the most efficient, remained unclear.
