求猜存钱罐中至少有多少钱.容易知道金币总的重量,接着背包. #include<cstdio> #include<iostream> using namespace std; #define N 10010 #define M 100000000 int dp[N]; ],we[]; int main() { int t; scanf("%d",&t); while(t--) { int em,fu; scanf("%d%d",&…
所谓的全然背包,就是说物品没有限制数量的. 怎么起个这么intimidating(吓人)的名字? 事实上和一般01背包没多少差别,只是数量能够无穷大,那么就能够利用一个物品累加到总容量结尾就能够了. 本题要求装满的,故此添加个限制就能够了. #include <stdio.h> #include <stdlib.h> #include <string.h> inline int min(int a, int b) { return a < b? a : b; }…
题意:给出猪罐子的空质量和满质量,和n个硬币的价值和质量,求猪罐子刚好塞满的的最小价值. 思路:选择硬币,完全背包问题,塞满==初始化为无穷,求最小价值,min. 代码: #include<iostream> #include<cstdio> #include<cstring> using namespace std; #define inf 10000000 int n,sum,empty,full,T; int v[600],w[600],dp[10050]; in…
