The fun thing about these sorts of tests if in figuring out how to do it a little bit differently. For example, I wanted to see if I could do it with a true one-liner (ie, no semicolons) with piecewise construction (ie, no nested ternaries). Here's my solution.

(Yes, it's ugly. But it works!)

    (1..100).each { |i| puts [i % 3 == 0 ? "Fizz" : nil, i % 5 == 0 ? "Buzz" : nil].join.first || i }
