Questions & Step-by-Step Solutions
Which of the following traversal methods can be used to create a mirror image of a binary tree?
Step 1: Understand what a binary tree is. A binary tree is a structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Know what a mirror image of a binary tree means. A mirror image means that the left and right children of all nodes are swapped.
Step 3: Learn about traversal methods. Traversal methods are ways to visit all the nodes in a binary tree. The common methods are pre-order, in-order, and post-order.
Step 4: Realize that any traversal method can be used to visit all nodes in the tree. This means you can use pre-order, in-order, or post-order to access each node.
Step 5: Understand that while traversing, you can swap the left and right children of each node to create the mirror image.
Step 6: Conclude that since all traversal methods allow you to visit each node, any of them can be used to create a mirror image of the binary tree.
