Sample solution for Balkan MO 2023 seems .. questionable?
The problem involves players removing stones sequentially and asking which will win with perfect play: the listed answer definitely doesn’t list all possible types of strategies.
The answer it gives may be right; in fact I bet it is correct (the second player), but does the qwen team offer the solution as correct including the logic? And is the solution logic correct?
