HDU1398Square Coins(母函数)】的更多相关文章

解题心得: 1.其实此题有两种做法,动态规划,母函数.个人更喜欢使用动态规划来做,也可以直接套母函数的模板 Square Coins Time Limit: 2000/1000 MS (Java/Others)    Memory Limit: 65536/32768 K (Java/Others) Total Submission(s): 12191    Accepted Submission(s): 8352 Problem Description People in Silverland…

题目类似于整数拆分,很明显用母函数来做. 母函数的写法基本固定,根据具体每项乘式的不同做出一些修改就行了.它的思路是从第一个括号开始,一个括号一个括号的乘开,用c1数组保存之前已经乘开的系数,即c1[j]表示在之前已经乘开过的那些括号处理后x的j次方的系数,c2数组是一个临时更新的统计数组,每处理一个括号就更新一遍c1数组即可. #include<iostream> #include<cstdio> #include<cstdlib> #include<cstri…
题意: 有17种硬币,每种的面值为编号的平方,比如 1,4,9,16.....给出一个数字,求组成这个面值有多少种组法? 思路: 用普通母函数解,主要做的就是模拟乘法,因为硬币是无限的,所以每个构造式中每一个项的系数都是1.我们只需要第n项的系数,大于n的并不需要,所以大于n的项就不用再做计算了. #include <bits/stdc++.h> using namespace std; ; int main() { freopen("input.txt", "r…

找单词 题意: 中文题,考虑是不是要写个英文题意..(可惜英语水平不够  囧rz)                (题于文末) 知识点: 母函数(生成函数): 生成函数有普通型生成函数和指数型生成函数两种(本题是普通型). 形式上,普通型母函数用于解决多重集的组合问题, 指数型母函数用于解决多重集的排列问题. 母函数还可以解决递归数列的通项问题(例如使用母函数解决斐波那契数列,Catalan数的通项公式). 普通母函数: 构造母函数G(x), G(x) = a0 + a1*x + a2* + a…
