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
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.)
It’s not complicated at all: en.m.wikipedia.org/wiki/Palindrome. Not really something that’s education-specific, in this instance (though I suppose it’s commonly used in entry-level programming classes since it’s a simple concept).
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”.
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.
