WebMorris Traversal is a method based on the idea of a threaded binary tree and can be used to traverse a tree without using recursion or stack. Morris traversal involves: Step 1: Creating links to inorder successors. Step 2: Printing the information using the created links (the tree is altered during the traversal) Step 3: Once the traversal has ... WebSteps to find preorder traversal using stack: Step 1: Create an empty stack and put the root element into it. i.e Stack-> 6. Step 2: Now check if the stack is non- empty. if so , then pop …
