It looks very weird, but if you put it like abab vs abba, it makes more sense

"()()" is an ambigram, which wikipedia describes as "visual palindromes", for whatever that's worth.

This is an unacceptable glitch in the universe.

It's time to reboot it with a patch.

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

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 took me a while but after converting to ascii in hex I get it

"())(" = 40 41 41 40

"()()" = 40 41 40 41

As long your strings aren't null terminated

What about ⊂⁠(⁠(⁠・⁠▽⁠・⁠)⁠)⁠⊃

Why would you do this to me 😭

Oh god, please no 😄

1212 isn't a palindrome, but 1221 is.

That's horrible and horrifying and I'm never gonna sleep again and also I hate you :(

Calm down, everyone. Brackets form a tree structure, and can be represented by a free magma, while strings with concatenation are equivalent to a free monoid. You're essentially asking for the two respective common involutory operations to be connected by this map, just because they're involutory, which put that way is a wild guess at best. In fact, reversing this string produces something outside the range of the map entirely, which is injective and so can't be surjective for combinatorical reasons.

... Yeah I might be the only person that finds that useful.

Had to take a break and come back later before it made sense.

I'm not saying I was having a good day before, but this made it that lil bit worse.

Thank you for letting me hate it as well.

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.

Wild stuff.

What about ))-((

Stupid brain, filling in the gaps when I didn't even want it to...

fuck that was unexpected

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