Data Structrues in competitive programming

Revision en1, by AmericanPsycho, 2017-08-15 23:16:56

Hi eveyone

What data structures are needed in competitive programming?
I know all stl structures, segment tree and BIT. But I have heard
others like treap, AVL tree, persistents, but I don't know if those
structures are really neccesary for competitive programming or
all their uses can be replaced by others and if not,
What are all the necessary data structures?
