Welcome to the tutorial on data structures! Data structures are essential for organizing and managing data efficiently in computer programs. In this guide, we will explore various data structures and their applications.

Basic Concepts

  • Arrays: A collection of elements stored in contiguous memory locations.
  • Linked Lists: A sequence of nodes where each node contains data and a reference to the next node.
  • Stacks: A Last-In-First-Out (LIFO) data structure.
  • Queues: A First-In-First-Out (FIFO) data structure.

Practical Examples

Here's a practical example of how arrays are used:

# Example of an array in Python
fruits = ["Apple", "Banana", "Cherry"]
print(fruits[0])  # Output: Apple

Advanced Data Structures

  • Trees: A hierarchical data structure consisting of nodes.
  • Graphs: A collection of nodes and edges that connect pairs of nodes.
  • Hash Tables: A data structure that maps keys to values.
