binary-search-tree

问题 I have an tree like: tree = [[[None,1,None],2,[None,3,None]],4,[None,6,[None,7,None]]] The numbers represent the root of each node, the none represent the children that have no value. For example, the main root is 4 and [[None,1,None],2,[None,3,None]] is the sub tree on the left and this [None,6,[None,7,None]] is he sub tree on the right. The principal root on the sub tree on the left is 2 etc etc... And my problem is that I want to insert a value in this tree. For example I want to add the

问题 I've heard of a new balanced BST data structure called a zip tree. What is the zip tree? How does it work? 回答1: At a high level, a zip tree is a randomized balanced binary search tree, that is a way of encoding a skiplist as a BST, and that uses a pair of operations called zipping and unzipping rather than tree rotations. The first bullet point - that zip trees are randomized, balanced BSTs - gives a feel for what a zip tree achieves at a high level. It's a type of balanced binary search tree

问题 My goal is to create a Binary Search Tree (BST) from a given string, using a preorder traversal. Eventually, I will use the BST to decode a binary message using Huffman encoding/decoding. My question/issue pertains to setting up the tree itself. (I already figured out how to decode the message after the set up.) Here is an example of what I'm trying to accomplish. (NOTE: This was provided in the assignment we were given. String: ^a^^!^dc^rb Here is what the tree should look like: My issue
