1027 Colors in Mars (20)（20 分）提问
People in Mars represent the colors in their computers in a similar way as the Earth people. That is, a color is represented by a 6-digit number, where the first 2 digits are for Red, the middle 2 digits for Green, and the last 2 digits for Blue. The only difference is that they use radix 13 (0-9 and A-C) instead of 16. Now given a color in three decimal numbers (each between 0 and 168), you are supposed to output their Mars RGB values.
Input
Each input file contains one test case which occupies a line containing the three decimal color values.
Output
For each test case you should output the Mars RGB value in the following format: first output "#", then followed by a 6-digit number where all the English characters must be upper-cased. If a single color is only 1-digit long, you must print a "0" to the left.
Sample Input
15 43 71
Sample Output
#123456#include <iostream>
using namespace std;
int s[13]={'0','1','2','3','4','5','6','7','8','9','A','B','C'};
int main(int argc, char** argv) {
int r,g,b;
scanf("%d %d %d",&r,&g,&b);
printf("#");
printf("%c%c",s[r/13],s[r%13]);
printf("%c%c",s[g/13],s[g%13]);
printf("%c%c",s[b/13],s[b%13]);
return 0;
}
