杭电ACM2010：水仙花数

#include <iostream>using namespace std;int main(){    int m, n;    int a, b, c,flag=0;    int x[1000];    while (cin >> m >> n)    {        if (m > n){            n = m + n;            m = n - m;            n = n - m;        }        for (int i = m; i <= n; i++){            a = i % 10; b = (i / 10) % 10; c = i / 100;            if (i == a*a*a + b*b*b + c*c*c){                x[flag] = i;                flag++;            }        }        if (flag == 0) cout << "no" << endl;        else{            for (int i = 0; i < flag-1; i++)  //因为从0开始                cout << x[i] << " ";            cout << x[flag - 1] << endl;      //flag-1为最后一位        }        flag = 0;    }    return 0;}

格式话输出是AC的关键
