纯C

跟着第一感觉走

#include <stdlib.h>
#include <stdio.h>

int main()
{
    int num;
    while(scanf("%d", &num) != EOF)
    {
        int tri = num * num * num;
        for(int i=1; i<65000; i += 2)
        {
            int sum = (i+(i+(num-1)*2))*num/2;
            if(sum == tri)
            {
                for(int j=0; j<num-1; j++)
                {
                    printf("%d+", i+2*j);
                }
                printf("%d\n", i+2*(num-1));
            }
        }
    }
    return 0;
