层序遍历 level-order traversal」从顶部到底部逐层遍历二叉树,并在每一层按照从左到右的顺序访问节点。 层序遍历本质上属于「广度优先遍历 breadth-first traversal」,也称「广度优先搜索 breadth-first search, BFS」,它体现了一种“一圈一圈向外扩展”的逐层遍历方式。 广度优先遍历通常借助“队列”来实现。队列...

层序遍历(level-order traversal)从顶部到底部逐层遍历二叉树,并在每一层按照从左到右的顺序访问节点。 层序遍历本质上属于广度优先遍历(breadth-first traversal),也称广度优先搜索(breadth-first search, BFS),它体现了一种“一圈一圈向外扩展”的逐层遍历方式。 1. 代码实现 package binary_tree_bfs import (...

This is how the code for In-order Traversal looks like: Example Python: definOrderTraversal(node):ifnodeisNone:returninOrderTraversal(node.left)print(node.data,end=", ")inOrderTraversal(node.right) Run Example » TheinOrderTraversal()function keeps calling itself with the current left child...
This is how the code for pre-order traversal looks like:Example Python: def preOrderTraversal(node): if node is None: return print(node.data, end=", ") preOrderTraversal(node.left) preOrderTraversal(node.right) Run Example » The first node to be printed is node R, as the Pre-...
For each completely specified binary tree in the input file, the level order traversal of that tree should be printed. If a tree is not completely specified, i.e., some node in the tree is NOT given a value or a node is given a value more than once, then the string ``not complete...
