题目来源:http://poj.org/problem?id=1014 题目大意: Marsha和Bill拥有一些弹珠.但是这些弹珠的价值不一样.每个弹珠的价值都是1到6之间的自然数.他们希望把这些弹珠分为两份,每份的总价值相等.然而,有时候是不存在这样的划分的(即使总的价值为偶数).比如弹珠的价值分别为1,3,4,4.写一个程序判断一些弹珠是否可以被分为价值相等的两份. 输入:每行代表一个测试用例,含6个非负整数.n1,...n6.ni表示价值为i的弹珠有多少个.测试用例最多20000个.输入…

http://poj.org/problem?id=1014 (题目链接) 题意 给出有分别价值为1,2,3,4,5,6的6种物品,输入6个数字,表示相应价值的物品的数量,问一下能不能将物品分成两份,是两份的总价值相等. solution 多年以前写的程序了,现在才写博客= =.这道题一看就是多重背包,所以我们用二进制把它拆分成01背包就很好做了,不知道的话就看<背包九讲>吧.. 首先我们把6种物品的总价值记为S,如果S%2==1,那么显然是无解的.考虑S%2==0的情况.我们把每个种物品用二…
