Functional Programming Lecture 5: Polymorphism & ADTs

Binary search trees are binary trees with elements stored at the interior nodes such that elements to the left of a node are smaller than

RECURSIVE BST OPERATIONS with more Java generics

Let's implement a BST class avoiding iteration. This will give us more practice with trees

Tree Equality: The Problem

Suppose we want to write a function that determines if two trees are equal: Is it polymorphic? ... Now we can define our polymorphic binary search tree:.

Search in a Binary Search Tree - LeetCode

Binary Search Tree Niche Basically binary search trees are fast at insert and lookup The next section presents the code for these two algorithms On average a binary search tree algorithm can locate a node in an N node tree in order lg(N) time (log base 2) Therefore binary search trees are good for "dictionary" problems where the code

The Binary Search Tree Class The binary search tree class will be derived from the binary tree class; hence all binary tree methods are inherited template class Search tree: public Binary tree {public: Error code insert(const Record &new data); Error code remove(const Record &old data); Error code tree search(Record

How to search in a binary search tree?

Search in a Binary Search Tree - LeetCode Search in a Binary Search Tree - You are given the root of a binary search tree (BST) and an integer val. Find the node in the BST that the node's value equals val and return the subtree rooted with that node. If such a node does not exist, return null.

What is a branch in a binary tree?

Branch: A path ending in a leaf node is called a branch. In the above figure, A?D?J?K is a branch. Binary TreeA binary tree is a finite set of nodes, which is either empty or consists of a root and two disjoint binarytrees called left subtree and the right subtree.

What is a binary tree OOP?

With this OOP structure, almost every operation has two methods: a one-line method on the BinaryTree that starts the computation, and a recursive method that works on the Node objects. For the lookup() operation, there is a BinaryTree.lookup() method that the client uses to start a lookup operation.

How do recursive search trees work?

Given a binary search tree and a "target" value, search the tree to see if it contains the target. The basic pattern of the lookup() code occurs in many recursive tree algorithms: deal with the base case where the tree is empty, deal with the current node, and then use recursion to deal with the subtrees.
