1027 Colors in Mars

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

进制转换：

#include <iostream>
#include <string>
using namespace std;

void convert(int i) {
	if (i >= 10) {
		cout << (char)('A' + i - 10);
	} else {
		cout << i;
	}
}

int main() {
	int a, b, c;
	cin >> a >> b >> c;
	cout << '#';
	int x, y;
	x = a / 13;
	y = a % 13;
	convert(x);
	convert(y);
	x = b / 13;
	y = b % 13;
	convert(x);
	convert(y);
	x = c / 13;
	y = c % 13;
	convert(x);
	convert(y);
	return 0;
