Post order traversal of a tree

Web16 Nov 2024 · Postorder: post-order traversal of the tree. Create Initially an empty tree without any nodes is created. The variable/identifier which must point to the root node is initialized with a NULL value. Search You always start searching the tree at the root node and go down from there. You compare the data in each node with the one you are looking … Web1 day ago · I am a beginner in C++ and I have a task to delete duplicate elements in a balanced binary tree using a pre-order traversal. I might be able to do this in a binary search tree, but I have no idea how to implement it in a balanced tree.
