CSC 172 DATA STRUCTURES

CSC 172 DATA STRUCTURES. CSC172_LEC11_TreesAVL.odp. A PROBLEM WITH BSTs. Common operations on balanced BST are O(log(n)) Alas, when the tree goes out of balance, performance degrades (worst case : chain O(n)) There are several data structures that modify the BST to maintain balance.
