题目

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

直接求

代码：

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

string Change(int n);

int main()
{
	int r,g,b;
	cin>>r>>g>>b;
	string s="#";
	s+=Change(r);
	s+=Change(g);
	s+=Change(b);
	cout<<s;
	return 0;
}

string Change(int n)	//转换格式
{
	string s;
	if(n/13<10)
		s+='0'+n/13;
	else
		s+='A'-10+n/13;
	if(n%13<10)
		s+='0'+n%13;
	else
		s+='A'-10+n%13;
	return s;
}
