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.
  • 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.
