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

解题思路

1.其实就是叫你把十进制的数转化为13进制输出。注意输入为0 0 0 的情况。

AC代码

#include<iostream>
#include<vector>
#include<queue>
#include<string>
using namespace std;
string radix_13(int a){
if (a == 0) {
return "00";
}
string tem = "";
while (a>0) {
int b = a % 13;
char c;
if (b > 9) {
c = (b - 10) + 65;
}else {
c = b + '0';
}
tem = c + tem;
a = a / 13;
}
if (tem.length()==1) {
tem = "0" + tem;
}
return tem;
}
int main(int argc, char *argv[])
{
int a,b,c;
//cout << int('A') <<endl;
cin >> a >> b >> c;
cout << "#" << radix_13(a)<<radix_13(b)<<radix_13(c)<< endl;
return 0;
}
