1027 Colors in Mars

1027 Colors in Mars （20 分）

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 Specification:

Each input file contains one test case which occupies a line containing the three decimal color values.

Output Specification:

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 its left.

Sample Input:

15 43 71

Sample Output:

#123456

#include 

char color[14] = {"0123456789ABC"};

int main(int argc, char** argv) {
	int red, green, blue;
	scanf("%d %d %d", &red, &green, &blue);
	printf("#%c%c", color[red / 13], color[red % 13]);
	printf("%c%c", color[green / 13], color[green % 13]);
	printf("%c%c", color[blue / 13], color[blue % 13]);
	return 0;
