Each subtask has a set of test cases, and you will get the points for the subtask if your solution passes all of its test cases. You can send multiple solutions for a task, and your final score is the highest score among them.
When you submit a solution for grading, the result for each test case is one of the following:
- WRONG ANSWER
- TIME LIMIT EXCEEDED
- OUTPUT LIMIT EXCEEDED
- RUNTIME ERROR (for example, memory limit exceeded or unhandled exception)
During the contest, you will see a single result for each subtask: the first result of a test case which is not ACCEPTED, or ACCEPTED if there are no other results.
