1027. Colors in Mars (20)

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

问题相当于把十进制的数转化成13进制。

代码：

#include <iostream>#include <cstring>#include <vector>#include <cstdlib>#include <cstdio>using namespace std;char itoc(int n){if(n<10) return n+'0';else return n-10+'A';}int main(){cout<<'#';for(int i=0;i<3;i++){int c;cin>>c;printf("%c%c",itoc(c/13),itoc(c%13));}}
