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

bdbd is not a palindrome but bddb is

bddb is my favorite word to pronounce

do you have to say it while flipping your finger up and down over your lips?

I think you just hacked my modem

Is it pronounced like that Super Troopers Porsche song?

Yes, baddragonbaddragon is, in fact, not a palindrome.

This is much easier to parse for me than the one in the post. Interesting. I guess letters are easier to abstract

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

Oh boy, they have some good ones. You've been missing out.

Edit: Quicksort has a nice one. SVD for linear/matrix operations too.

I'm pretty sure I've seen even better ones that could almost stand as a YouTube video but I can't remember where now

[–] [email protected] 9 points 2 months ago (1 children)

I love that the word ambigram can be made to look as an ambigram whereas palindrome - wtf, could have done so much better with naming that guys.

Well that's just mean.

This is an unacceptable glitch in the universe.

It's time to reboot it with a patch.

[–] [email protected] 44 points 2 months ago* (last edited 2 months ago)

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 has ruined my day.

[–] Kaelygon 21 points 2 months ago* (last edited 2 months ago) (1 children)

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

As long your strings aren’t null terminated

What kind of monstrous bug prone language would do that?

1212 isn't a palindrome, but 1221 is.

[–] [email protected] 14 points 2 months ago

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

[–] istoff 13 points 2 months ago

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

[–] [email protected] 13 points 2 months ago

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

[–] [email protected] 13 points 2 months ago* (last edited 2 months ago) (5 children)

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.

[–] [email protected] 5 points 2 months ago (1 children)

yeah but that's just like your opinion man

Thank you for letting me hate it as well.

[–] [email protected] 9 points 2 months ago

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.)

[–] istoff 7 points 2 months ago (1 children)

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.

[–] [email protected] 13 points 2 months ago (1 children)

The reverse would be ((-))

[–] [email protected] 7 points 2 months ago* (last edited 2 months ago) (1 children)

Wouldn't it be ()-)( as a palindrome?

[–] [email protected] 4 points 2 months ago (1 children)

That's a palindrome because the reverse is the same. The comment above you shows that the one above isn't a palindrome since the reverse is different, not showing a palindrome

[–] [email protected] 4 points 2 months ago

Yeah I realized

[–] iAvicenna 5 points 2 months ago

fuck that was unexpected

[–] voracitude 5 points 2 months ago

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

[–] jaybone 4 points 2 months ago

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