FizzBuzz Station

Uh oh! I overthought fizzbuzz:

The following Ruby snippets aren’t quite the same as the automaton above (this Haskell version is actually closest to that), but here’s a couple of Regexp solutions in a style that I haven’t seen before. They have a kind of Turing-tape flavor to them.

puts (1..100).map { |n| ‘1’*n+” }.join.
  gsub(/(1{5})Buzz’).gsub(/(1{3}):/,’Fizz’).gsub(/.*:|(z)d+/,’1’)




puts (1..100).map { |n| ‘x’*n+”#{n}n” }.join.
  gsub(/(xxx)d/,’Fizz’).gsub(/[05]$/,’Buzz’).gsub(/x|d*(.+?)d*/,’1’)

I’m not much of a golfer, so please let me know in the comments if you tighten them up any.
