Details
The author, who is rated around 800, solves the ABC425 problem. The implementation involves adding the initially black cells to a queue and then checking if the surrounding cells can be painted black. If a surrounding cell can be painted black, it is added to the queue. This process continues until all possible cells have been painted black. The problem statement mentions that up to 10^100 operations may be required.
