前面一章介绍了BST的结构和一些简单的基本功能,例如:insert,findMin,nextLarger等等.这一节主要讲解一些BST的delete node操作还有BST的height的分析以及一些潜在的问题.即本节主要包括以下2个部分: 1,Analysis of deletion 2,Tree height analysis 一:Node deletion delete node的过程是需要依靠前一章的知识,需要了解nextLarger的过程和含义.然后在此基础之上,我们可以将删除node…

Overview AVL tree is a special binary search tree, by definition, any node, its left tree height and right tree height difference is not more than 1. The purpose of AVL tree is to try best to reduce the search time complexity. if the binary search tr…
