Study Notes
Tree Data Structure
- A tree data structure represents a hierarchical tree structure with connected nodes.
Binary Tree
- In a binary tree, each parent can have a maximum of two children.
Tree Correspondence
- An ordered tree in graph theory corresponds to an ordered tree in computer science.
Tree Traversal
- Recursion is a useful technique for tree traversal because it allows for efficient exploration of the tree structure.
Node Properties
- Every node in a tree may have associated properties, such as values or keys.
Uncommon Applications
- Games are not a common application of trees in computer science.
Efficient Search
- Trees are commonly used to store data in a way that enables efficient search algorithms via tree traversal.
Space Partitioning
- K-D trees are used for space partitioning, including binary space partitioning, in computer-generated imagery.
Non-Tree Graphs
- Cyclic graphs, which can be created within file systems, are an example of non-tree graphs.
Abstract Syntax Trees
- Abstract syntax trees are commonly used to represent the source code of computer languages in a structured format.
