Thoughts
Thought this was the toughest one yet. Grid problems like this always seem to give me troubles. Part 2 was particularly tough because I had the example working but not the real one and that is always tough to debug. Turns out my reverse number stuff was falling apart on zeros but it took me forever to realize that was what the problem was.
Takeaways
Grids are tricky and debugging is much trickier when the example isn't helpful.
The Good
Critical thinking practice
The Bad
Zeros
