Flatten a binary tree to linked list
WebApr 5, 2024 · Given a Linked List, create a Complete Binary Tree. The idea is to first find the middle node of the linked list and make it the root of the tree. We then recursively do the same for the left and right halves. The algorithm has mainly two steps. 1) Get the middle of the linked list and make it the root of the tree.
