Hi guys, i've tried to solve this problem with A*. I came with pull distance as heuristic and calculate the distance table with Floyd's algorithm. I also have put deadlock detector (for Simple and Frozen) on my code. Is there something i miss? Or do you have any other suggestion?

I am very happy if i can discuss with you guys. Thanks before for your help :)

I know some interesting optimisations which helped me get TLE 78 but I don't understand how to use A* in this problem. Let's discuss it. My email is imoskovchenko72@gmail.com
