There is a box that contains 20 identical balls. two players take turns removing balls from the box. in each turn, a player can choose to remove 2 or 3 balls. the player who is forced to remove the last ball loses. can you use backwards induction to find a winning strategy for one of the players?

just examine how the end game will go

this can !
