Questions & Step-by-Step Solutions
Which of the following is NOT a type of binary tree traversal?
Step 1: Understand what a binary tree is. A binary tree is a data structure where each node has at most two children.
Step 2: Learn about binary tree traversal. Traversal means visiting all the nodes in the tree in a specific order.
Step 3: Identify the common types of binary tree traversal. The three main types are: in-order (left, root, right), pre-order (root, left, right), and post-order (left, right, root).
Step 4: Look at the options given in the question. One of the options is 'Cross-order'.
Step 5: Check if 'Cross-order' is a recognized type of binary tree traversal. It is not.
Step 6: Conclude that 'Cross-order' is NOT a type of binary tree traversal.
