    When did all the 4-pointers change to either 3 points or 5 points?

      2 days ago: we found that the overwhelming majority of 4 point problems were better classified as either 3 or 5 point problems, so that distinction no longer exists.

    I think the test case is too much.

    I need a bit of help after I had 250 successful cases something went wrong and I can't figure out what.

      Try some cases, for example:

      not not not False

      Congratulations on successfully convincing yourself that over 1000 people have solved this problem incorrectly.

      Your program is what is incorrect, as you have not considered all cases. Specifically, there is a case where you output nothing.

      Why are we booing him? The input is literally in python code format, which means that if you input into a python shell, it will actually run. That means that the problem is easily cheesed with python's eval that allows you to run python code in string form. Don't believe me? Look at all the top pypy3 submissions. It's literally one line of code.

    Never thought I'd ever see a problem where the assembly solution is shorter than C++.

      The format the input is given in is not a coincidence.

    This problem might be a bit easy in Python

        You can still do it in one line on Python 3 :)

          Right. Python's an interpreted language. Gotta remember that.

          On an unrelated note, I wonder if I can get AHK to solve equations by highlighting them using the same idea? Would save me so much time.
