nice! better than the top one.

Hey, that's illegal...

Oh, and a trick: post a Suggestion with your translation in the Discourse when you've published it. That gives people the opportunity to reply to that comment, for which you will get a notification, eg. when there is an issue with your translation.

( Also, someone will probably reply to the Suggestion closing it - free point! If they're nice, they might upvote the Suggestion - 'nother free point! :D )

Please see this Issue.

Also, it's better to have fixed and random Submit tests. I usually at least copy over the example tests as fixed tests, but edge cases such as 0 streets could have been included as well.

Also, for an 8kyu kata, showing inputs on test failure is a good idea.
