Here's my code , i kind of optimized it so it doesn't give TLE or some memory errors.
But i get wrong result on testcase: 5,8,10.
I'm sort of lost with it , i can't find any logical faults.

pls help im stuck -.- i did it in something like 10 ways this one got the best results.

You declare for every function call a new queue , thats to much memory. That's the reason for the TLE. The WA you get is cause you check function is wrong.

Go trough the whole field and if you find a free block, then call bfs.
