    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.

      I know! They went a bit overboard with the test cases. Pretty sure it took 30 seconds.

    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

      Python 2, that is. Python 3 still requires work.

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

          Technically you can do it with 0 lines on python

          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.

          I mean that's why it's not 3 points?
