给出Andy和各怪物的能量, 攻击力, 防御力，和迷宫的地图，请你计算一下 能量/耗时 的最大值。



当Andy走到有怪物的地方时，Andy会先进行攻击，然后怪物攻击，然后Andy……当一方的能量小于等于0时攻击停止，并且小于等于0的一方死亡。攻击时，每次对方损耗的能量为己方的攻击力减去对方的防御力。

-Andy and gives each monster energy, attack power, defense, and the map of the maze, you calculate the energy/time consuming maximum. When Andy went to the place where there are monsters, Andy will first attack, then attack the monster, and then Andy ...... when one side of the energy is less than equal to 0:00 attack stopped, and the death of one is less than or equal to 0. Attacks, each other energy loss by subtracting one' s attack each other' s defense.
