Morris Pre Order Traversal

Short summary

Morris Preorder Traversal achieves O(1) space binary tree traversal by temporarily threading nodes instead of using recursion or stack. Nodes are visited before left traversal; threads are created at inorder predecessors and removed on return, restoring the original tree.

• •Achieves O(1) space complexity for binary tree preorder traversal
• •Uses temporary threading of nodes instead of recursion or stack
• •Restores original tree structure by removing threads on return
