.find_all works but .select is what we're looking for here.

They are aliases, and most folks prefer select.

looks good. are you familiar with ruby's to_proc method? its super common and would help you shorten this a bit.

@jaybobo Ahh gotcha. So something more like this input.map(&:capitalize) ?

ruby has a cool enumerable called .grep which is handy here for particular use cases like this one.

@jaybobo Something more like this input.grep(/^[c,d]/i) ?
@jaybobo Please review whenever you have a second.
