Problem Statement |
| | In some computer game, you are surrounded by monsters, and you are to kill them all. Each monster has some number of life points and damage points, and you also have some number of damage points. Life points represent the amount of life left in a monster. As long as a monster has one or more life points, it remains alive. Damage points represent the number of life points that are taken away from an enemy by a single attack. At every turn, you are attacked by each of the living monsters, and then you attack exactly one of them (at the same turn).
You are given a int[] life, the number of life points that each monster starts out with, a int[] damage, the number of damage points each monster has, and an int yourDamage, the number of damage points you have. The ith elements of life and damage represent the life points and damage points for the ith monster. Return the minimal number of life points you must start out with in order to kill all the monsters. At the end of the fight, you must have one or more life points remaining. |
