Solution: Binary Tree Preorder Traversal
Explore the binary tree preorder traversal technique using Morris traversal, a depth-first search method that visits nodes in root-left-right order without recursion or extra stack space. Understand the algorithm that modifies and restores tree pointers to traverse efficiently with O(n) time and O(1) space complexity.
