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

主要考察进制转换，代码如下：

#include <iostream>#include <string>#include <algorithm>using namespace std;string radix13(int x){int rem,quo=x;string result="";while(quo>0){rem=quo%13;if(rem<10)result+=(rem+'0');else{rem-=10;result+=(rem+'A');}quo/=13;}if(result.size()==0)result+='00';if(result.size()==1)result+='0';reverse(result.begin(),result.end());return result;}int main(void){int digit[3],i=3;while(i--)cin>>digit[i];cout<<"#";for(i=2;i>=0;i--)cout<<radix13(digit[i]);return 0;}
