Writing checkers

Mike Mirzayanov!

It's strictly recommended to write checkers in Testlib.h

Learn it here if you don't know

Using testlib.h

Write a normal checker in testlib's format and compile it.

You are done!

Manual

The checker will be called with four arguments:

checker <input path> <output path> <answer path> <report path>

You should read from the first three paths and write the checker comment to report path.

Your program should return 0 when the solution is accepted.

Return anything except 0 and 7 when the solution is not correct.

When returning 7, the first token in the report file should be the score of the testcase.

The time limit for the checker is 30 seconds.
