Abstract: Binary Search Trees (BSTs) are fundamental data structures in computer science; because of their implicit key sorting and linked node structure, they provide effective sorting and simple ...

Now that we’re getting into more complex data structures, having more complex operations, it’s helpful to have a tool for visualization. Here’s a tool developed by David Galles, formerly of University ...

Before we begin with AVL trees, watch this short video on tree rotation. We’ll use tree rotation with AVL trees and later on with splay trees, so it’s important you understand what’s going on with ...

All species on Earth, both living and extinct, are related. We know this because of a biological tool called the tree of life. This "tree" takes the form of a diagram that maps the relationships ...

Social Networking is a smart social networking system that aims to compete with Facebook. It allows users to create profiles, add friends, search for other users, and get recommendations for new ...

Dr. James McCaffrey of Microsoft Research says decision trees are useful for relatively small datasets and when the trained model must be easily interpretable, but often don't work well with large ...

2. 从基本的题目理解考虑，想到leaf node的情况。如果判断了leaf node, 那其他node应该就是可以recursive。 直接在isBalanced上面recursive. 关键return false的判断情况：如果有个node是null, 那么同一行相邻的那个，一旦有了children,那么就说明两个分支的depth已经是>=2了，那么就 ...

Abstract: We study the detection error probability associated with a balanced binary relay tree, where the leaves of the tree correspond to N identical and ...

Both a sorted array and a binary tree can let you look up an element in log(N) time. However I would expect a sorted array to be faster in practice because of the constant factor. However inserting ...
