Binary Tree Vertical Order Traversal https://leetcode.com/problems/binary-tree-vertical-order-traversal/ 这道题让我们竖直的遍历树,和按层遍历非常相似。我第一次做的时候,使用的是递归的形式,发现顺序会出错。 因此还是要借助按层遍历的思路,将树逐层的加入一个队列,然后再取出来进行处理。 遍历的时候,...

If we are given a binary tree and we need to perform a vertical order traversal, that means we will be processing the nodes of the binary tree from left to right. Suppose we have a tree such as the one given below. If we traverse the tree in vertical order and print the nodes then...
What is the vertical order traversal? 4.2. How do you vertically print a binary tree? 4.3. How do you know if a binary tree is full? 4.4. What is the top view of the binary tree? 4.5. What are cousins in a binary tree?
Given therootof a binary tree, returnthe vertical order traversal of its nodes' values. (i.e., from top to bottom, column by column). If two nodes are in the same row and column, the order should be from left to right. Example 1: ...
