Detailed explanation-1: -PostOrder traversal is used to delete the binary tree. Binary tree traversals give quick searching, insertion, and deletion in cases where the tree is balanced. The root node value is printed at last in traversal only after visiting the left subtree and right subtree.
Detailed explanation-2: -The postorder traversal is one of the traversing techniques used for visiting the node in the tree. It follows the principle LRN (Left-right-node). Postorder traversal is used to get the postfix expression of a tree.
Detailed explanation-3: -Pre-order: Used to create a copy of a tree. For example, if you want to create a replica of a tree, put the nodes in an array with a pre-order traversal. Then perform an Insert operation on a new tree for each value in the array. You will end up with a copy of your original tree.
Detailed explanation-4: -Preorder traversal (NLR): it is a topologically sorted order (because a parent node is processed before any of its child nodes is done) and it is usually used to create a copy of tree or compare two binary trees.
