Solution Review: Print Pre-Order Traversal
Let’s go through the detailed solution review of the challenge given in the previous lesson.
Solution
In pre-order traversal, the node is visited first, then its left child (or left subtree), and then its right child (or right subtree). This approach is followed recursively for each node in the tree until we reach the leaf node. Refer to the following illustration to better understandthe algorithm.
