Hello everyone!

We all know that JOI has a rich collection of high quality problems. But a fact is that almost all past problems are in Japanese, so many of us can't attempt to try / solve them.

Since Codeforces Polygon now supports setting OI Problems, I and some of my friends (ruhan.habib39, TheeLooser, Bruteforceman) took and in initiative to translate the problems and upload them to Codeforces.

We will be having our first contest, JOI Spring Camp 2013 Day 1, today at 6:05 PM UTC+06

You need to join the Bangladesh Olympiad in Informatics Training Group to participate in the contest. You'll get full feedback about the tests, However, Codeforces currently doesn't show subtasks separately, also doesn't show points appropriately for single test. Hope you'll cope with the problems.

Let's discuss the problems here after the contest ends.

Note: We created this contest for our own training, so we will be participating too.
