WebFirst, we will see the recursive solution then I will show you how to solve it without recursion. Approach: Recursive Approach: The approach will be very simple, do any of the tree traversal ( inorder, preorder, postorder, BFS or DFS) and check if the given element is present. Run This Code Code: WebThe following operations are performed to traverse a binary tree in pre-order using a stack: Start with root node and push onto stack. Repeat while the stack is not empty. POP the top element (PTR) from the stack and process the node. PUSH the right child of PTR onto to stack. PUSH the left child of PTR onto to stack. Consider the following tree.

WebTo convert the above recursive procedure into an iterative one, we need an explicit stack. Following is a simple stack-based iterative algorithm to perform preorder traversal: iterativePreorder (node) if (node = null) return s —> empty stack s.push (node) while (not s.isEmpty ()) node —> s.pop () visit (node) if (node.right != null)
