Study Notes
Data Structures Overview
- Data structures are used to organize data in a computer's memory to enable efficient storage and retrieval.
Queue Data Structure
- A queue is a First-In-First-Out (FIFO) data structure, where data exits in the same order it enters.
- A key feature of a queue is that it has a beginning and end.
Binary Tree Data Structure
- A binary tree is a data structure organized like an upside-down tree, with each node having at most two children.
- The purpose of a binary tree is to enable efficient search, insertion, and deletion of data.
Choosing Data Structures
- Computer programmers decide which data structures to use based on the specific requirements of their program, such as efficiency, scalability, and complexity.
Simple Data Structures
- An example of a commonly used simple data structure is an array.
