You made a step up of this kata and hadn't solved the original? lol

I also need to solve some of yours, I just haven't had the time lately.

it should not have taken me this long to solve this kata... great kata as always

why tf cant i import typing

Don't complete this kata jet, but writting code 4 days. All tests to 11x11 are completed, but 13x13 - so much time working (12000 ms +) Cashing don't help.

So interesting kata, thanks) I will be make it :)

its good practice because n.left or n.right could be falsy values

please make a python translation, i need a dopamine boost when i break the kata (idk any hacky things about js)

Very nice puzzle!

I enjoyed solving this kata, but my solution, which uses backtracking with constraint satisfaction, only passes 204 tests!

Try changing your approach. This greedy algorithm takes ~2^65 steps for "worst-case" 128-bit numbers.

4. golf it! :-)
