第一次见这么长的题目……
多重背包,可以说背包九讲的模版题。

#include <iostream>#include <stdio.h>#include <stdlib.h>#include <string.h>#include <math.h>#include <algorithm>using namespace std;int v;int dp[105],p[105],h[105],c[105];void ZeroOnePack(int cost,int weight){    for(int i=v;i>=cost;i--)        dp[i]=max(dp[i],dp[i-cost]+weight);}void CompletePack(int cost,int weight){    for(int i=cost;i<=v;i++)        dp[i]=max(dp[i],dp[i-cost]+weight);}void MultipliesPack(int cost,int weight,int amount){    if(cost*amount>=v)CompletePack(cost,weight);    else    {        for(int k=1;k<amount;)        {            ZeroOnePack(k*cost,k*weight);            amount-=k;            k<<=1;        }        ZeroOnePack(amount*cost,amount*weight);    }}int main(){    int t,m;    scanf("%d",&t);    while(t--)    {        memset(dp,0,sizeof(dp));        scanf("%d%d",&v,&m);        for(int i=1;i<=m;i++)        {            scanf("%d%d%d",&p[i],&h[i],&c[i]);            MultipliesPack(p[i],h[i],c[i]);        }        printf("%d\n",dp[v]);    }    return 0;}
