Binary search tree to show “Preorder”, “Inorder” and “Postorder”

WebJan 26, 2024 · For Preorder, you traverse from the root to the left subtree then to the right subtree. For Post order, you traverse from the left subtree to the right subtree then to the root. Here is another way of representing the information above: Inorder => Left, Root, Right. Preorder => Root, Left, Right. Post order => Left, Right, Root. WebConstruction of the binary tree from Inorder and Postorder Traversal Example: Inorder Traversal: [4, 2, 5, 1, 3] Postorder Traversal: [4, 5, 2, 3, 1] Now from the postorder traversal we can see the right most element, node 1 is the root node. From Inorder traversal we can see that node 3 is on right of root node 1, and others on left. reach out hertfordshire
