Here's my solution!

I used a ternary for the letter grade function, and I was going to try to do something fancy with Array.map for the other function, but I ended up doing a regular Array.each loop.

This is very easy to read. 👍

Ruby provides many methods to built-in classes. In particular, all these methods on Enumerable are available to instances of Array.

Consider rewriting this method to sort the input array by the length of the elements, then just plucking off the answer.

Or, if you scan through those Enumerable methods, you might find min_by which basically does the whole thing for you. But what's the fun in that?

Thanks very much for the feedback!
