You can definitely get this done in a single line. Look into other ways of using .each.

Ah. I'm guessing ruby supports assignment if a key doesn't exist? E.g.

words.each do |word|
  list[word] += 1
end

Also, I'm not sure what you mean about looking into other ways of using .each. Any suggestions on what to look for?

Check the Ruby documentation for the Each. Should be a big hint as to how you can get that down to a single line. Your eg code is pretty close, but you can totally get it down to just one line. 😃

Oh. You mean by using a single line block?

words.each { |word| list[word] += 1 }
