KY15 abc

刷题链接: .

题目描述:

设a、b、c均是0到9之间的数字,abc、bcc是两个三位数,且有:abc+bcc=532。求满足条件的所有a、b、c的值。

输入描述:

题目没有任何输入。

输出描述:

请输出所有满足题目条件的a、b、c的值。a、b、c之间用空格隔开。每个输出占一行。

示例1:

输入:

 

输出:

 

我的代码:(双重循环即可解决问题)

#include
int main(){ for(int a=0;a<=9;a++) { for(int b=0;b<=9;b++) { double c=(532-a*100-b*110)/12.0; int d=int(c); if(c==d&&d>=0&&d<=9) printf("%d %d %d\n",a,b,d); } } return 0;}

巧妙解法:

利用该题的特点,c+c=…2,c只能为1或者6,若c为6,b只能为6,a无解排除,c只能为1,分别算出b为2,a为3。
