TLE from unordered_set C++

Правка en5, от haochenkang, 2022-03-24 21:28:06

Hello Codeforces community!

I have a question regarding question B in the recent CodeTon round.

My solution passed all pretests, but TLE on test 22 in the main tests. My code is: 150736681

I used an unordered_set to keep tracking of the seen elements. However, when I changed it to set, the solution passed main tests too. I have always thought that unordered_set are faster than set. Can someone please explain to me what's happening here?

Thanks for any help!
