<一道题>abc+cba=1333,求满足条件的abc的值，香港服务器，香港服务器，隐含条件a!=0,c!=0
这类东西，无非就是穷举法。见下面代码：
#include <stdio.h>#include <stdlib.h>/**abc + cba = 1333 **a = ?*b = ?*c = ?*/int main(int argc ,char **argv){int a=0;int b=0;int c=0;int index = 0;printf();for(a = 1 ; a <= 9 ; a++)//a [1,9] {for(b = 0 ; b <= 9; b++)//b [0,9]{for(c = 1 ; c <= 9; c++)//c [1,9]{if(1333 == (100*a + 10*b + c + 100*c + 10*b + a)){index++;printf(,index,a,b,c);//多谢1楼仁兄，找到了，却没有注意英文语法，香港虚拟主机，已改found及I}}}}printf();return 0;}
运行结果;
