有 n 个骑士想决战.每个骑士都有能力值(互不相同),且身上带有一些金币.如果骑士 A 的能力值大于骑士 B ,那么骑士 A 就可以杀死骑士 B ,并获得骑士 B 身上的所有金币.但就算是骑士也不会残忍过度,他们最多只会杀死 k 个骑士.对于每一位骑士,请你求出在杀掉所有他能杀的人(只有他能杀人别人不动)后他身上金币的最大值. Solution 注意到"互不相同"这个弱化条件,考虑对能力值从小到大排序,那么每个骑士能且只能杀他前面的人.所以动态维护前 \(k\) 大和就好了 (题意有点…

解题思路 将骑士按力量从小到大排序,到第i个骑士的时候,前面的i-1个骑士他都可以击败,找出金币最多的k个. 用multiset存金币最多的k个骑士的金币数,如果多余k个,则删除金币数最小的,直到只有k个数字. 我就是因为没有用multiset在最后5分钟被hack了. 代码 #include <bits/stdc++.h> using namespace std; typedef long long ll; int n,k; //输入,p表示力量,c表示金币,idx表示输入时的位置 stru…
