Expert Solution & Answer
Chapter 21, Problem 1MC
Program Description Answer
A binary tree is a collection of nodes in which each node “has at most two successors”.
Hence, the correct answer is option “D”.
Expert Solution & Answer
Explanation of Solution
Binary tree:
- Binary tree is a hierarchical structure to represent the data. The element of the tree is called as a node or item.
- Here, the branches are used to connect the nodes.
- Each node may have zero, one, or two children.
- A node that does not have a superior node is called the root node.
- The root node is the starting node, and it is the ancestor for all other nodes in the tree.
- The set of children node in a binary tree form a subtree rooted at that node.
- A node that does not have a children is called as a leaf node or an end node.
Explanation for incorrect options:
Has no successor:
A binary tree may have zero, one, or two successor node. So, it cannot be predicted that a binary tree has no successor.
Hence, option “A” is wrong.
Has one successor:
A binary tree may have zero, one, or two successor node. So, it cannot be predicted that a binary tree has one successor.
Hence, option “B” is wrong.
Has exactly two successors:
A binary tree may have zero, one, or two successor node. So, it cannot be predicted that a binary tree has exactly two successors.
Hence, option “C” is wrong.

This is a question that I have and would like someone who has experiences with scene graphs and entity component systems to answer.For context, I am currently implementing a game engine and currently I am debating on our current design.Our current design is we have a singular game component class that every component inherits from. Where we have components like SpriteRendererComponent, Mehs Component, etc. They inherit from this GameComponent class. The point of this is being able to have O(1) access to the scene to being able to modify components to attach more components with the idea of accessing those components to specific scene objects in a scene.Now, my question is what kinds of caveauts can this cause in terms of cache coherence? I am well aware that yes its O(1) and that is great but cache coherence is going to be really bad, but would like to know more explicit details and real-life examples such as write in RAM examples on how this is bad.
