简单动归，，

完全背包类型的吧 ，，，，

代码如下；

#include <cstdio>
#include <cstring>
#define M 10005
int coin[21] = {1 ,8 ,27 ,64 ,125 ,216 ,343 ,512 ,729 ,1000 ,1331 ,1728 ,2197 ,2744 ,
                3375 ,4096,4913 ,5832 ,6859 ,8000 ,9261};
long long dp[M];
int n;
int main ()
{
    dp[0] = 1;
    for(int i = 0; i < 21; i++)
    {
        int v = coin[i];
        for(int j = v; j < M; j++)
            dp[j]+=dp[j-v];
    }
    while(~scanf("%d",&n))
    {
        printf("%lld\n",dp[n]);
    }
    return 0;
}
