numbers, and then deleting the place where the person who buried him was originally located. Finally calculated from the beginning of the Count 1th, the last can survive the number p, then from the first person in front of you you are safe (you stand in the 1th place), that is n–p. The principle of this conversion is obvious.This is to find you in front of the first person to start you are safe;This man will bury the man who had just been killed and stand in the place of the slain man.Exercises
