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.
