Well, here's my first crack at it.

<Reveal this spoiler or all spoilers in this node or all in this thread>

and a few modifications to allow for multiple longest strings, and repeated chars (although, the output still only outputs one of the longest string, but the hash contains the info for each longest string).

<Reveal this spoiler>

It ain't pritty, but it works (I think?).

Update:Oops! Fixed general soultion. Needed to trim roots as well as branches. Thanks LR.
