    Please explain what this does and how it does it.  I don’t care if it is 70% the same as another answer; that answer is also unclear.  And each answer should stand alone; even if Tmuxer’s answer is deleted, yours should still be understandable. … … … … … … … … … … … … … … … … … … Please do not respond in comments; edit your answer to make it clearer and more complete. … (Cont’d) Commented May 1, 2022 at 19:25

    (Cont’d) …  P.S. If you copy somebody else’s answer and modify it, you should give credit to the original answer, both by linking to it and by citing the author’s name.  If you were really using the above code before yesterday, you should probably say so, because it sure looks like you copied Tmuxer’s answer.  P.P.S. If you are Tmuxer, please don’t post two separate answers that are 70% the same.  Merge your accounts and post one answer that contains both solutions (with explanations!).
