Answer: C) NodesExplanation:A binary tree consisting only of nodes (empty tree) is also a binary tree.3. There is a unique node in a binary tree called its ___?Parent Left child Right child RootAnswer: D) RootExplanation:There is a unique node in a binary tree called its root.4...
Given a binary tree containing digits from0-9only, each root-to-leaf path could represent a number. An example is the root-to-leaf path1->2->3which represents the number123. Find the total sum of all root-to-leaf numbers. For example, 1 / \ 2 3 The root-to-leaf path1->2repres...
In subject area: Computer Science A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a fe...

Over the years various interesting questions about the statistics of such trees were investigated (e.g., height and path length distributions for a randomly selected tree). Binary trees find an abundance of applications in computer science. However, recently Seroussi posed a new and interesting ...
Many of the "programming puzzle of the day", or "dev job interview questions" relate to binary trees. This repo contains a binary tree implementation in a Go package, as well as code that solves puzzle-or-problem-of-the-day questions.I...
We will examine all these questions in the next section. Even if we show the code to be unique and efficient, the method described to this point is highly impractical. In Section 4.4.2, we will describe a more practical algorithm for generating the arithmetic code for a sequence. We will...
