大意是给你1个整数n,问你能拆成多少种正整数组合.比如4有5种: 4 = 4;  4 = 3 + 1;  4 = 2 + 2;  4 = 2 + 1 + 1;  4 = 1 + 1 + 1 + 1; 然后就是母函数模板题……小于n的正整数每种都有无限多个可以取用. (1+x+x^2+...)(1+x^2+x^4+...)...(1+x^n+...) 答案就是x^n的系数. #include<cstdio> #include<cstring> using namespace std;…

这是道典型的母函数的题目,可以看看我的母函数这一标签上的另一道例题,里面对母函数做了较为详细的总结.这题仅贴上代码: #include"iostream" using namespace std; #define N 130 ],b[N+]; int main() { int n,i,j,k; ) { ;i<=n;i++) {a[i]=;b[i]=;} ;i<=n;i++) { ;j<=n;j++) ;k+j<=n;k+=i) { b[k+j]+=a[j]; }…

题目链接:hdu 1028 Ignatius and the Princess III 题意:对于给定的n,问有多少种组成方式 思路:dp[i][j],i表示要求的数,j表示组成i的最大值,最后答案是dp[i][i].那么dp[i][j]=dp[i][j-1]+dp[i-j][i-j],dp[i][j-1]是累加1到j-1的结果,dp[i-j][i-j]表示的就是最大为j,然后i-j有多少种表达方式啦.因为i-j可能大于j,这与我们定义的j为最大值矛盾,所以要去掉大于j的那些值 /*******…

题意: 输入一个数n,求组合成此数字可以有多少种方法,每一方法是不记录排列顺序的.用来组成的数字可以有1.2.3....n.比如n个1组成了n,一个n也组成n.这就算两种.1=1,2=1+1=2,3=3=1+2=1+1+1,而1+2和2+1只能算一种.n最大为120. 思路:关于母函数的原理不讲了.讲怎么实现几个括号相乘. 思路: 我们要算的n是等于120,把其简化为5,就是说设n最大为5,道理一样的.5一共有7种方法对吗!自己手写吧. 如果想要得出结果,那么一共有5个括号要相乘,分别如下: 为…
