    Let us substitute: ( - x, ) - y
    Thus ()() becomes xyxy
    ())( becomes xyyx
    Now clearly it can be seen, even while high, that the second one is and the first isn’t

    Yes it does bother me a little that the letters in the latter half of my username can’t be written backwards. (Well, some can, and the p can become a q, but then it’s not a p any more.)

    Best palindrome I ever come across is boob. I heard Jimmy Carr say it, but he could be repeating somebody else’s joke.

        Yea but I’m just generally dumb in a pool of smart people. Not like I’m using palindromes in everyday conversation so when I see it I gotta look it up. Like when I saw a Fibonacci sequence and mentioned that it looks like something I’ve seen before but couldn’t remember where. This doesn’t even touch on why the syntax mentioned is a palindrome 😆

          All it means is if you were to reverse the order of the characters, you’d get the same string you started with. So “dog” isn’t a palindrome because when you reverse it, you get “god”. “dog god” is a palindrome, though, because if you read it backwards, it’s also “dog god”.

          Nobody uses palindromes in everyday conversation.

          They are only useful as nerd jokes, interesting math facts (with no real world application), and stupid leetcode algorithms (with no real world application).

          Nearly everybody here knows about them because nearly everybody here is exposed to lots of instances of those 3 categories. You could be feeling out of the loop, but you shouldn’t at all get impostor syndrome from it.

            That’s actually a great response and just wanted to let you know I appreciate it. I’m actually pretty good with where I’m at and just joking around but your messages made me feel good and I wanted to let you know that and I appreciated it

    for those too lazy to google,
    palindrome /păl′ĭn-drōm″/ noun A word, verse, or sentence, that is the same when read backward or forward. “madam; Hannah; or Lewd did I live, & evil I did dwel.”

    () () backwards is )( )(
    () )( backwards is () )(

    This is especially terrible when lying in bed. With a keyboard or pen and paper you can make sense of it, it hurts my brain a bit to visualize it though.

    A palindrome is about symbols. Not the visual representation of those symbols.
