Your strategy fails with 3 1 2 100 5 4. (a - b = 2 is greater than 4 - 5 = -1, but you want to pop first.) Update: The reason why you want to pop first is because then the game goes: 1: pop 4 2: shift 3 1: shift 1 2: pop 5 1: pop 100 2: shift 2and your score is 95. If you shift first then the game goes: 1: shift 3 2: pop 4 1: shift 3 2: shift 1 1: pop 5 2: pop 100 1: shift 2and your score is 90.
