Tasks

Common Files

• Technical Overview (38 kB): Technical instructions. Also contains information on the grading system and shows the compilation options used by the grading server.
• Task Overview Sheets (38 kB): Task information sheets of all three days, including e.g. execution time and memory limits.

Task descriptions are PDF files. The test data for each task is stored into a ZIP archive, where each test case is located in its own subdirectory. Each subdirectory contains the input and output files ("taskname.in" and "sample.out") for the respective test case. The first test case, i.e. subdirectory "1", is always the same as the example given in the task description.

The test data for RLE is somewhat different than for other tasks. First, two examples are given in the task description, and these correspond to test cases in directories "1" and "2". Second, the checking of an answer requires using an additional test program rlechk whose source (rlechk.cpp) is included in the archive. To check the correctness of an answer, use this program with the following command line:

        rlechk rle.in rle.out sample.out

where "rle.out" is the answer to be checked. For all other tasks it is sufficient to check that the answer is equivalent to "sample.out".
