WebApr 5, 2024 · Consider the following tree: Example of Binary Tree. If we perform a preorder traversal in this binary tree, then the traversal will be as follows: Step 1: At first the root will be visited, i.e. node 1. Node 1 is visited. Step 2: After this, traverse in the left subtree. Now the root of the left subtree is visited i.e., node 2 is visited. WebIf the tree is empty, we create a new node and return it. If the node value is smaller than the root node, it is inserted into the left subtree, otherwise it is inserted into the right subtree. In preorder_traversalthe function, we implement the function of traversing the binary tree in preorder. We first visit the root node, then traverse the left
