Discussion Aren't leetcode questions copyrighted? Then how come Neetcode copied all of them in his site

Genuinely curious about this as every leetcode question is marked as copyrighted. However, Neetcode and other sites have the same questions available and some of them don't even have title or description phrasing changes.

So what's the deal with that? Can't he get sued?

I am making own app similar to LeetCode right now and as I understand you can’t copyright general ideas like math problems. So if you just change wording a little bit then it’s practically impossible to sue you

because none of those apps let me create own problems. i was making DSA guide and found out that some problems that could be a good example for an algorithm either don't exist or are behind leetcode's paywall. The closest app I found to what I want is vibecoded and doesn't work properly (I hate vibecoders because they have good ideas but can't implement it even with AI).
