abc - cattle-off

Title Description

Set a, b, c are numbers between 0 and 9, abc, bcc two three-digit, and has: abc + bcc = 532. Seeking to satisfy all the conditions a, b, c of the value.

Enter a description:

Entitled without any input.

Output Description:

Please all output values ​​a, b, c satisfies the condition the subject. Separated by a space between a, b, c. Each output per line.

Problem-solving ideas

First, brute force

Directly through the loop to find qualified a, b, c 

Note that the initial conditions, a, b, respectively, as the hundreds digit, so from a traversing.

 1 #include <stdio.h>
 2 int main()
 3 {
 4     int a,b,c;
 5     for(int a = 1;a<=9;a++)
 6       for(int b = 1;b<=9;b++)
 7           for(int c = 0;c<=9;c++)
 8               if(a*100+b*10+c + b*100+c*10+c == 532)
 9                   printf("%d %d %d",a,b,c);
10   
11 }

Second, when I solve problems, not violent method used, but the use of the characteristics of the problem directly calculate the answer.

abc + bcc = 532 

Counting from the single digits, c = 1 c = 6 or maybe only cases

Bitwise discussed separately, not need to traverse! Direct negative case c = 6, i.e., the calculated value a, b, c of.
