wrong video isnt it?
Shayan
It is supposed to be the solution discussion of Codeforces Round 963. Did I mistakenly add another video somewhere?
Problem names/links are from other contest
Oh, you are right. Thanks.
Ig only the titles are misplaced.
Thanks. Fixed.
Is there a container that always maintains the elements in sorted order, allows me to access any k-th largest/smallest element in O(log n) complexity, and also supports insertion and deletion of elements in O(log n) complexity? THANKS~~
i think you are looking for this.
COOL
but be careful, orderd set is not exactly O(log(n)) but O(log(n) * constant) and this constant may cause a time limit (rarely).
oh i know，thanks
you can do it with compression and fenwick/segment tree.
thanks！
