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 the left.

Sample Input

15 43 71

Sample Output

#123456

题目大意：

给定三个十进制数，把他们转换为13进制数并输出，并在最前面输出#。

思路及分析：

由于0~168的十进制转换为13进制不会超过两位数，这个两位数为(num / 13)(num % 13)构成的数字。

AC代码：

#include<iostream>

using namespace std;

int main(){
	char a[14] = {"0123456789ABC"};
	cout << "#";
	for(int i = 0; i < 3; i++){
		int temp;
		cin >> temp;
		cout << a[temp/13] << a[temp%13];
	}
	return 0;
}
