Ping game - Lycée Val de Durance (Pertuis) Colegiul National Emil Racovita (Cluj)

We use a row of counters, white on one side and black on the other.
Starting with a number of n white counters which all need to be turned to black according to the following rule: When we indicate a counter, the counters either side are turned to black. How should we proceed?
We have developed a formula that determines the number of moves required in a ping game. Additionally, we have devised a strategy to solve the game irrespective of the initial number of coins flipped to black. Moreover, we’ve explored similar concepts as those applicable to a single row of coins, but extended to two rows.
