B. Knights of a Polygonal Table

standard output

Unlike Knights of a Round Table, Knights of a Polygonal Table deprived of nobility and happy to kill each other. But each knight has some power and a knight can kill another knight if and only if his power is greater than the power of victim. However, even such a knight will torment his conscience, so he can kill no more than kk other knights. Also, each knight has some number of coins. After a kill, a knight can pick up all victim‘s coins.

Now each knight ponders: how many coins he can have if only he kills other knights?

You should answer this question for each knight.

Input

The first line contains two integers nn and k(1n105,0kmin(n?1,10))(1≤n≤105,0≤k≤min(n?1,10)) — the number of knights and the number kk from the statement.

The second line contains nn integers p1,p2,,pnp1,p2,…,pn (1pi109)(1≤pi≤109) — powers of the knights. All pipi are distinct.

The third line contains nn integers c1,c2,,cnc1,c2,…,cn (0ci109)(0≤ci≤109) — the number of coins each knight has.

Output

Print nn integers — the maximum number of coins each knight can have it only he kills other knights.

Note

Consider the first example.

  • The first knight is the weakest, so he can‘t kill anyone. That leaves him with the only coin he initially has.
  • The second knight can kill the first knight and add his coin to his own two.
  • The third knight is the strongest, but he can‘t kill more than k=2k=2 other knights. It is optimal to kill the second and the fourth knights: 2+11+33=462+11+33=46.
  • The fourth knight should kill the first and the second knights: 33+1+2=3633+1+2=36.

In the second example the first knight can‘t kill anyone, while all the others should kill the one with the index less by one than their own.

In the third example there is only one knight, so he can‘t kill anyone.

题意:给你n个人,每个人都有一个力量值和一些金钱

现在假设一个人可以攻击任意人,如果攻击力量值比他低的人

就可以得到那个人的金钱,输出每个人攻击最多k个人后最多可以有

多少金钱.

这个题是真的坑

最后FST了,55555,比赛的时候没有注意到一个小知识点

求k个人可以得到最多的钱的时候如果是用二叉平衡树的set容器的话

如果容器中有重复的元素的话会自动去重

multiset集合容器:

------ 和set的区别:set容器中所有的元素必须独一无二,而multiset容器中元素可以重复

但是由于不太会用multiset 所以使用vector,每次都排个序,一样的结果

思路在代码中

#include<bits/stdc++.h>
using namespace std;
const int maxn = 1e5+5;
int n,k;
struct node {
    int p,id;
} a[maxn];
bool cmp(node a,node b) {
    return a.p<b.p;
}
vector<long long> v;
long long c[maxn];
long long ans[maxn];
int main() {
    ios::sync_with_stdio(false);
    cin>>n>>k;
    for(int i=0; i<n; i++) {
        cin>>a[i].p;
        a[i].id=i;
    }
    for(int i=0; i<n; i++) {
        cin>>c[i];
    }
    //k=0时特殊处理
    if(k==0) {
        for(int i=0; i<n; i++) {
            printf("%d ",c[i]);
        }
        printf("\n");
        return 0;
    } else {
        //对力量值排序
        sort(a,a+n,cmp);
        ans[a[0].id]=0;
        long long sumk=0;//前k大和
        for(int i=1; i<n; i++) {
            if(v.size()<k) {
                /在k个数之前时  加上前面这些数的cost
                v.push_back(c[a[i-1].id]);
                sumk+=c[a[i-1].id];//前i个数的和
            } else if(c[a[i-1].id]>v[0]) {
                //前面数中最大的k个数的和
                sumk+=c[a[i-1].id]-v[0];//更新最大值
                v[0]=c[a[i-1].id];//更新第k大值
            }
            sort(v.begin(),v.end());//对于k个数重新排序
            ans[a[i].id]=sumk;
        }
        for(int i=0; i<n; i++) {
            printf("%lld ",ans[i]+c[i]);
        }
        printf("\n");

    }
    return 0;
}
