Note for C++ users: Do not use the STL input/output streams for tasks with big input and output files. In the current version of GCC, it's much slower than using the C-style streams and you may run out of time just reading and writing the files.
The translations below have been prepared by the teams competing in the on-site competition in Tartu. The Norwegian and Swedish students work with the English texts, thus we do not have the translations in these languages. We also can't provide translations in any other languages.

A simple timer program (timer.exe in the Windows package, timer in the Linux package) is included. It takes exactly 1 second to run this program on the evaluation computers. By comparing the time it takes to run this program on your computer, you can see how the speed of your computer compares to the speed of the evaluation computers.
For task REGS, a checker program (REGSCHECK.exe in the Windows package, REGSCHECK in the Linux package), which verifies the correctness (but not optimality) of the REGS.OUT with respect to the REGS.IN and gives informative error messages.
