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.

样例

=================================================

Sample input:

15 43 71

Sample output:

#123456

思路

=================================================

进制转换题，但是因为输出只有两位数字，只需要输出x/13和x%13就行

完整代码

=================================================

#include <iostream>

using namespace std;
void deal(int x){
	char s[13] = {'0', '1', '2', '3', '4', 
		'5', '6', '7', '8', '9', 'A', 'B', 'C'};
		cout << s[x/13] << s[x%13];
}
int main() {
	int a, b, c;
	while(cin >> a >> b >> c){
		cout << "#";
		deal(a);
		deal(b);
		deal(c);
	}
}
