Can we please improve the quality of editorials a bit.. if I am not able to get any clue on how to approach the problem during the contest then I can't just out of the blue understand the editorial with just stating the process rather than helping with some intuition behind the problem.

Problem F editorial was written so badly in abc 380. Other low effort editorials too. Is it just me who feels this?

    F's editorial was clear imo. You can interpret "is_first_player_win" as "can_first_player_win" and then simulate the game. The editorial also explains the time complexity and that it does not go in infinite recursion (game always ends). What are you confused about?
