游戏规则很简单,用箭杀死免子即可.  箭是一种消耗品,已知有M种不同类型的箭可以选择,并且每种箭都会对兔子造成伤害,对应的伤害值分别为Di(1 <= i <= M),每种箭需要一定的QQ币购买.  假设每种箭只能使用一次,每只免子也只能被射一次,请计算要消灭地图上的所有兔子最少需要的QQ币. Input输入数据有多组,每组数据有四行: 第一行有两个整数N,M(1 <= N, M <= 100000),分别表示兔子的个数和箭的种类: 第二行有N个正整数,分别表示兔子的血量Bi(1 &…

题目: 最近,减肥失败的湫湫为发泄心中郁闷,在玩一个消灭免子的游戏. 游戏规则很简单,用箭杀死免子即可. 箭是一种消耗品,已知有M种不同类型的箭可以选择,并且每种箭都会对兔子造成伤害,对应的伤害值分别为Di(1 <= i <= M),每种箭需要一定的QQ币购买. 假设每种箭只能使用一次,每只免子也只能被射一次,请计算要消灭地图上的所有兔子最少需要的QQ币. 思路: 每个箭有两个属性伤害和花费,这两个需要固定下一个来才能找出最小的花费. 既然是找最小的花费,那我们就优先确定下伤害来就可以,对血量…

贪心算法+优先队列. 很明显是应当先消灭blood值大的,那么注意到,对于少blood值的,能灭大blood值的箭必定能消灭小blood值的,所以,可以先排序,在消灭一个blood值的时候,选择一个小Q币的即可. #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> #include <queue> #define LL __int64 usin…

将兔子的血量从小到大排序,箭的威力也从小到大排序, 对于每仅仅兔子将威力大于血量的箭增加队列,写个优先队列使得出来数位价钱最少.. #include<stdio.h> #include<queue> #include<algorithm> #include<iostream> #include<functional> using namespace std; const int maxn=100010; struct tt { int d; in…
