so abstract

I benchmarked it and found it to be at least twice as slow as the ternary implemenatation. It looks nice though.

It's a question of what's more idiomatic. See Avdi Grimm's master work: Confident Ruby

The description specifies: "Input will always be a non-negative integer."

Don't think this solution is correct: when n and m are both negative, this solution will give you the positive result, when 0 should be returned.

I like the consistency of logic.

Only seems to be happening for Clojure & Haskell for me. Ruby, Python, Coffeescript & Javascript solutions still seem to be working.

I'm surprised this hasn't been voted up. It's cleaner and easier to read than the current #1 solution.

I'm fairly certain this violates the spirit of the exercise =)

I like it!

Isn't this a little unnecessary? Sure, it's mathematically smart, but will become innacurate quickly.

Is there a way to change your profile picture?

Didn't know about the tr method. Good to know :)
