Hidden File Validation

To prevent a solution that just outputs a saved solution or something similar, we will be implementing a hidden file second test.

We have now posted a check for just printing the solution vs finding one via code.
and updated the leaderboard.

Sorry to say, only 2 solutions left right now.
Hope to see a lot more soon.

What do you do for that hidden file validation?

I can see my solutions failed, probably due to this reason, however I am 100% sure I don't have stored anywhere a solution. I only limit my code to run for a limited amount of seconds. My code is in C++. Have you had an issue with other C++ implementations?

I see that in the online judge there is a post that says

"If the First test fails, and the second passes, then, you need to submit code that can process anything it can receive"

What exactly do you mean by "process anything it can receive"? Does it mean ignore any invalid input and continue processing valid input? or fail at the first invalid input regardless of previous valid inputs?

What exactly do you mean by "process anything it can receive"?

It means we are using a hidden dataset for validation, if your code is able to process the original dataset, then it should pass both tests.

Thanks, I already found the problem.
