Which traversal method is 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 for every node, the left and right children are swapped.
Step 3: Learn about pre-order traversal. In pre-order traversal, you visit the current node first, then the left child, and finally the right child.
Step 4: Apply pre-order traversal to create a mirror image. Start at the root node, swap its left and right children, then recursively do the same for the left and right children.
Step 5: Repeat this process for each node in the tree until all nodes have been processed.
