Given a binary tree, collect a tree's nodes as if you were doing this: Collect and remove all leaves, repeat until the tree is empty. Example: Given binary tree 1 / \ 2 3 / \ 4 5 Returns[4, 5, 3], [2], [1]. 思路:我最开始的思路是求出每一个节点的depth,并且给res[depth]...

Step 1: Define the Binary Tree Firstly, we need to create the binary tree structure. Here, we’ll define a simple Node class: class Node: def __init__(self, data): self.data = data self.left = None self.right = None This class represents a node in the binary tree, which contains...
root(left/right). Then, we begin printing these groups of nodes while moving from left to right, and in case there are two or more nodes at the same level, we print them from top to bottom. So, if we print the above binary tree in vertical order, the output will be as follows -...
