jnjosh / fizzbuzz.hs
Last active December 10, 2015 14:49
Learning Haskell for fun. This gist is a log of changes I make to the fizzbuzz while learning. The revision history is the interesting part.
-- details: standard fizzbuzz, n % 3 = fizz, n % 5 = buzz, n % 15 = fizzbuzz
-- usage: ghci> fizzbuzz [1..100]
checkFizzbuzz :: Int -> String
checkFizzbuzz n
| mod n 15 == 0 = "fizzbuzz"
| mod n 5 == 0 = "buzz"
| mod n 3 == 0 = "fizz"
| otherwise = show n
