1027 Colors in Mars

1027 Colors in Mars (20 point(s))

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<iostream>
using namespace std;
void print(int x){
	if(x>=0&&x<=9) printf("%d",x);
	else printf("%c",x-10+'A');
}
void fun(int n){
	int d1 = n / 13;
	int d2 = n % 13;
	print(d1);
	print(d2);
}
int main(void){
	int r,g,b;
	scanf("%d%d%d",&r,&g,&b);
	printf("#");
	fun(r);fun(g);fun(b);
	printf("\n");
	return 0;
