上网搜了一下这道题的解法,主要有两个方法,一种是采用母函数的方法,一种是采用0/1背包的方法. 先说一下母函数,即生成函数,做个比喻,母函数就是一个多项式前面的系数的一个整体的集合,而子函数就是这个多项式每一项前面的系数.主要用于解决组合问题,类似于钱币的组合问题.利用母函数解题时,首先要写出表达式,通常是多项式的乘积形式,类似于:(x^(v[K]*n1[K])+x^(v[K]*(n1[K]+1))+x^(v[K]*(n1[K]+2))+...+x^(v[K]*n2[K])). 例如,对于有n种…

acm与oi很大的一个不同就是在输入格式上.oi往往是单组数据,而acm往往是多组数据,而且题目对数据格式往往各有要求,这8道a+b(吐槽..)涉及到了大量的常用的输入输出格式.https://wenku.baidu.com/view/1753515189eb172dec63b715.html 这篇文章是对这8道题的总结.为了我的方便和懒惰,就不放代码了..…

Big Event in HDU  HDU1171 就是求一个简单的背包: 题意:就是给出一系列数,求把他们尽可能分成均匀的两堆 如:2 10 1 20 1     结果是:20 10.才最均匀! 三种解法: 多重背包的优化与否:(1031MS) #include<iostream> #include<stdio.h> #include<algorithm> #include<string.h> using namespace std; ]; ],b[];…
