Convert a Binary Search Tree to a sorted Circular Doubly-Linked List in place. You can think of the left and right pointers as synonymous to the predecessor and successor pointers in a doubly-linked list. For a circular doubly linked list, the predecessor of the first element is the last e...

tail of the doubly linked list. For each leaf node in the inorder traversal, set the left pointer to tail and tail’s right pointer to the current leaf node. Also, update the corresponding left or right pointer of the parent node tonullto remove the leaf nodes from the binary tree. ...
One of the goals for a binary search tree is to speed up the search for a particular node, so having to step through a linked list to find the node would not be an improvement. To get the benefit of the tree, the nodes should be roughly balanced on both sides of the root. Ideally...
