WebMar 31, 2024 · We have discussed the below methods for postorder traversal. 1) Recursive Postorder Traversal . 2) Postorder traversal using Stack. 2) Postorder traversal using two Stacks. Approach 1. The approach used is based on using an unordered set to keep track of visited nodes and a while loop to traverse the tree. WebInorder : 1 6 12 20 35. Naive Approach. We can see that the first element in the pre-order traversal is always the root of the tree and the rest of the elements are a part of the left and right sub-tree. As the tree is BST, so all the elements smaller than root are present in the left sub-tree, and elements greater than root are present in the right sub-tree.

WebMar 24, 2024 · BST is used to implement multilevel indexing in database applications. BST is also used to implement constructs like a dictionary.
