Advent Programming Contest 2013

An Advent calendar is a special calendar used to count or celebrate the days in anticipation of Christmas. Advent calendars typically begin on December 1 and provide a window to open until December 24. Usually they have windows, which you can open each day containing some chocolate or other stuff. But what is better to kill some time until Christmas, Hanukkah, Yule, Kwanzaa, Diwali, Boxing Day, etc. than an Advent calendar giving you a programming problem every day?

The Advent Programming Contest 2013, organized by the IEEE Student Branch Klagenfurt will provide a new problem every day from December 1st to December 24th. On Saturdays and Sundays, new problems will appear at 12:00 Central European Time, on workdays at 18:00 CET. You can submit solutions any day until the contest ends on December 26. You can choose to use C, C++, Java, Python or Perl as programming language. The programming tasks can be solved with short programs (typically less than 100 lines of code). Until a solution is correct you can submit your program as often as you want (but please don't spam our server). Your score depends on the number of correct solutions and the time and trials you needed to solve the problem. Winners will be announced after closing of the contest.

The event is open to everyone. If you want to participate, please register at http://mooshak.nes.aau.at/ When you register please indicate if you bleong to the group University, Pupils or other.
This is an individuals competition, not a team contest - be fair!
