题目:http://acm.hdu.edu.cn/showproblem.php?pid=1171 题意:把商品分成两半,如不能均分,尽可能的让两个数相接近.输出结果:两个数字a,b且a>=b. 思路:01背包. 先把商品的总价值计算出来,sum/2做为背包的容量. 然后讲同种商品的多件,存储为不同商品 同样价值的形式,也就是我们用一个一维数组来存储,不用一个二维或是两个一维数组来存. 感想:好久没有做背包的题目了,今天来做,忘了好多思路,这提醒着我,学习不能一直都在学新东西,也要及时的复习.…

题目地址:HDU 1171 还是水题. . 普通的01背包.注意数组要开大点啊. ... 代码例如以下: #include <iostream> #include <cstdio> #include <string> #include <cstring> #include <stdlib.h> #include <math.h> #include <ctype.h> #include <queue> #incl…

/* 题意: 输入一个数n代表有n种物品, 接下来输入物品的价值和物品的个数: 然后将这些物品分成A B 两份,使A B的价值尽可能相等也就是尽量分的公平一些,如果无法使A B相等,那么就使A多一些: 思路: 先计算这些物品的总价值,然后从这些物品中去一些出来,使他们的价值尽可能的接近总价值的一半, 由此可以想到用01背包的思路: 背包容量是总价值的一半,物品体积等于物品的价值:   */     #include <cstdio> #include <cstring> #incl…

题目链接 题意:给出n个物品的价值v,每个物品有m个,设总价值为sum,求a,b.a+b=sum,且a尽可能接近b,a>=b. 题解:01背包. #include <bits/stdc++.h> using namespace std; ],dp[],n,v,m; int main() { ) { memset(dp,,sizeof(dp)); ,cnt=; ;i<n;i++) { scanf("%d%d",&v,&m); sum+=v*m; w…

题目链接: id=3211">poj3211  hdu1171 这个题目比1711难处理的是字符串怎样处理,所以我们要想办法,自然而然就要想到用结构体存储.所以最后将全部的衣服分组,然后将每组时间减半,看最多能装多少.最后求最大值.那么就非常愉快的转化成了一个01背包问题了... . hdu1711是说两个得到的价值要尽可能的相等.所以还是把全部的价值分为两半.最后01背包,那么这个问题就得到了解决.. 题目: Washing Clothes Time Limit: 1000MS   Me…
