Select all that apply. Which of the following are methods of traversing a binary tree?
A) LeftOrder traversal
B) PreOrder traversal
C) FrontOrder traversal
D) InOrder traversal
E) PostOrder traversal

Question

Quizplus · Accepted Answer

Traversal of a binary tree means visiting every node in the tree exactly once in a systematic order. Among the given options, only PreOrder traversal, InOrder traversal, and PostOrder traversal are valid methods of traversing a binary tree.

- PreOrder traversal visits the root node first, followed by the left subtree, and then the right subtree.
- InOrder traversal visits the left subtree first, followed by the root node, and then the right subtree.
- PostOrder traversal visits the left subtree first, followed by the right subtree, and then the root node.

LeftOrder traversal and FrontOrder traversal are not valid methods of traversing a binary tree.
