Binary Search Tree大量减少了查找、插入、移除元素的操作步骤,下面将实现一个二叉搜索树。 2. 实现二叉搜索树 Binary Search Tree 创建一个 playground,导入上一篇文章二叉树 Binary Tree创建的二叉树BinaryNode。并创建BinarySearchTree.swift文件,其代码如下: publicstructBinarySearchTree<Element:Comparable>{publicprivate...
We do that so we can use our lowest value as an easy baseline to compare with our other values as we “sink down” back to the bottom of the tree while making our comparisons and swaps along the way. Graphic/Animation thanks toVisuAlgo.net ...
LeetCode 235. Lowest Common Ancestor of a Binary Search Tree 因为是二叉搜索树,所以可以根据值的大小判定是属于根节点的左子树还是右子树。 如果都是在左子树部分,那么最低公共祖先一定属于当前节点的左子树; 如果都是在右子树部分,那么最低公共祖先一定属于当前节点的右子树; 否则当前节点一定是最低公共祖先(为...
To see what happens in a depth-first traversal approach, let’s look at another example of a partially explored tree: Notice the ordering of our discovered nodes in the collection. They are not left-to-right as the nodes appear visually in the tree. They are the opposite. They go from ...
