This should be best practice as the higher-upvoted code is less clean using single-letter variable names.

Nice, I was looking for a way to do it in a single regex. Stuck on the leftover spaces.

I am having a problem runnning my result... The execution runs out, and I think it's because of the exmaple_test('1000000R1000000R1000000R1000000',1000000000000)
Anything yoiu suggest I do?
I am aware my algorithm isn't optimized, but it was calculating everything perfectly

A path is invalid if it meets any of the following criteria:
...
the mousehole is located along the straight path of a wall (K's mousehole must be located at a convex/concave corner position to be valid)

It's that case.

Hey, guys and especially the author, case 2R4R4R4R2 - is normal case, so please review it , so it must be 16, but test says - null.

Thank you for the explanation.
