Silly job interview questions in Haskell
The Personal blog and musings of Chris Penner, a designer, developer and future opsimath.
I write a helper function "fizzle" here which converts a number into its appropriate string so I can keep the "printing" logic separate, which is good programming style in Haskell as it makes things easier to both test and reason about. The nice thing about that is that functions are composable and have very clean boundaries, which means we don't need to intermingle the syntax of a for-loop with our logic. Lastly we add one more pattern match which handles all invalid inputs (either negative numbers or empty lists) and simply assert that they have no valid combinations.
