解题思路:

母函数模板题。

AC代码:

#include <iostream>
#include <cstdio>
using namespace std;

int main(){
    int n;
    while(~scanf("%d",&n)){
        int c1[130],c2[130];
        for(int i = 0; i <= n; i++){
            c1[i] = 1;
            c2[i] = 0;
        }
        for(int i = 2; i <= n; i++){
            for(int j = 0; j <= n; j++)
                for(int k = 0; k+j <= n; k += i)
                    c2[j+k] += c1[j];
            for(int j = 0; j <= n; j++){
                c1[j] = c2[j];
                c2[j] = 0;
            }
        }
        printf("%d\n",c1[n]);
    }
    return 0;
}
