1027 Colors in Mars (20)（20 分）
People in Mars represent the colors in their computers in a similar wayas the Earth people. That is, a color is represented by a 6-digitnumber, where the first 2 digits are for Red, the middle 2 digits forGreen, and the last 2 digits for Blue. The only difference is that theyuse radix 13 (0-9 and A-C) instead of 16. Now given a color in threedecimal numbers (each between 0 and 168), you are supposed to outputtheir Mars RGB values.
Input
Each input file contains one test case which occupies a line containingthe three decimal color values.
Output
For each test case you should output the Mars RGB value in the followingformat: first output "#", then followed by a 6-digit number where allthe English characters must be upper-cased. If a single color is only1-digit long, you must print a "0" to the left.
Sample Input
15 43 71
Sample Output
#123456
Analysis:
upper means "大写"。。。。
