Remove Node in Binary Search Tree 解答 从BST中移除一个节点是比较复杂的问题,需要分好几种情况讨论。 如这篇文章,就讨论了删除节点 1.有无左右子树 2.只有右子树 3.只有左子树 三种情况。 一种简单些的思维是只考虑删除节点是否有右子树(因为第一个比删除节点大的节点可能出现在右子树,不会出现在左子树)...

Definition of Binary Search Tree: 1.Every node in the left subtree must be less than the current node 2.Every node in the right subtree must be greater than the current node Here the tree in Figure 2 is a binary search tree. Finding a data in a Binary Search Tree ...
Binary search tree. Latest version: 1.1.1, last published: 9 years ago. Start using node-binary-search-tree in your project by running `npm i node-binary-search-tree`. There are no other projects in the npm registry using node-binary-search-tree.
You are given therootof a binary search tree (BST) and an integerval. Find the node in the BST that the node's value equalsvaland return the subtree rooted with that node. If such a node does not exist, returnnull. Example 1: ...
B-tree is a special type of self-balancing search tree in which each node can contain more than one key and can have more than two children. It is a generalized form of thebinary search tree(BST). It is also known as aheight-balanced m-way tree. ...
