Finding the element closest to a value can be done in O(lg(n))O(lg(n)) (again, if the BST is balanced!). Weaknesses: Poor performance if unbalanced. Some types of binary search trees balance automatically, but not all. If a BST is not balanced, then operations become O(n)O(n...

Binary Search Trees in the Real-World Scott Mitchell 4GuysFromRolla.com Update January 2005 Summary:This article, the third in a six-part series on data structures in the .NET Framework, looks at a common data structure that isnotincluded in the .NET Framework Base Class Library—binary tre...
Binary search trees can be used to build efficient Sets that perform. lookups and inserts in □□(□□□) time, which is fairly efficient. As weve seen in class, Sets are useful for applications where you need to look things up by a "key" like checking airline tickets or looking up ...
The structure now looks like a trie of binary search trees. Use this observation and standard update techniques for balanced binary trees and tries to obtain logarithmic update times.

Summary:This article, the fourth in the series, begins with a quick examination of AVL trees and red-black trees, which are two different self-balancing binary search tree data structures. The remainder of the article examines the skip list data structure. Skip lists are an ingenious data stru...
