题意：
数学上有个水仙花数，他是这样定义的：
“水仙花数”是指一个三位数，它的各位数字的立方和等于其本身，比如：153=1^3+5^3+3^3。
现在要求输出所有在m和n范围内的水仙花数。解答：
哈哈，先遍历100~999所有数，检查是否满足水仙花数的条件，然后就可以直接用啦，只有四个数153,370,371,407
然后注意输出格式，第一次不小心Presentation error.
1: #include<stdio.h>
2: #include<stdlib.h>
3: int id[4]={153,370,371,407};
4: int main(){
5: int m,n,i;
6: while(scanf("%d %d",&m,&n)!=EOF){
7: int flag=0;
8: for(i=0;i<4;i++){
9: if(m<=id[i]&& id[i]<=n){
10: flag++;
11: if(flag!=1)
12: printf(" ");
13: printf("%d" ,id[i]);
14: }
15: }
16: if(flag==0)
17: printf("no");
18: printf("\n");
19: }
20: }
