Answer is neither, description does specify that released block should be merged with adjacent block but its not being tested.

If block is released and it has adjacent blocks on left and right, which adjacent block gets to have released block?

you are making this problem to O(N^2) time, it can be solved in N time

nice solution!

Description should really make clearer that islands are based on the Moore neighbourhood ( 8-n'b'hood ) and not the von Neumann neighbourhood ( 4-n'b'hood ).

I can read the current description both ways, and I tend to the 4-n'b'hood when reading it.

Examples do not specify!

Like the sqlite module, or more than that?

just you need to get where expression and replace '' with ' in string value

This kata was decided to stay.

Thanks for this solution!

Funny coding challenge to exercise with.

Having to do parsing makes me not want to start this. I think it would be more enjoyable if the queries are given in some ADT already. Make a separate 4-kyu parsing problem for the language if need be.

2nd Time I Got Top answer, lets go

Tests will never try to free an unallocated pointer (at least in Python).

There appear to be random tests in Python now, can you confirm that they are missing in other languages?

brilliant!
