Exploring Practical Applications of Data Structures in Daily Life
Written on
Introduction to Data Structures in Everyday Scenarios
In the tech world, companies like Amazon, Apple, Adobe, Cisco, and others place a strong emphasis on your proficiency with Data Structures and Algorithms. These elements are fundamental to solving real-world challenges and are often central to technical interviews. Let's delve into some relatable examples of how these structures manifest in our daily lives.
Examples of Arrays
Arrays are widely used in various applications:
- Contact List: Your phone's contact list is organized in an alphabetical array. Take a look at your own contact list for a firsthand experience! 😅
- Movie Ticket Booking: Booking a movie ticket exemplifies a 2D array, as you select a seat by specifying a row and column (like E6).
- Image Processing: This involves manipulating images, treating them as 2D arrays of pixels.
Examples of Stack
Stacks are essential in various operations:
- Expression Evaluation: Stacks help evaluate infix, postfix, and prefix expressions by pushing operators and operands onto the stack.
- Undo/Redo Operations: When you use undo (Ctrl-Z) or redo (Ctrl-Y) in applications like Word, stacks manage these commands behind the scenes.
Examples of Queue
Queues are integral in scenarios such as:
- Printer Service: When sending multiple documents (like PDFs A, B, and C) to print, they are processed in the order they were submitted (First Come First Serve).
- Server Requests: Multiple user requests to a server are queued, ensuring each is served in the order received.
- Game Player Sequence: In multiplayer games like LUDO, player turns are managed using circular queues.
Examples of LinkedList
Doubly Linked Lists are used in:
- Navigation in Google Drive: The previous and next buttons for files utilize this structure.
- Browser Navigation: Forward and backward browsing uses a doubly linked list to track history.
- Media Players: The next and previous song features in apps like Spotify are classic examples.
Examples of Graph
Graphs feature prominently in:
- Social Media Apps: Each user is a node, with edges representing friendships.
- Google Maps: Cities are nodes connected by edges that represent routes, utilizing algorithms like Breadth First Search for pathfinding.
Examples of Tree
Trees play a significant role in:
- Auto-Suggestion: The search bar's auto-suggestion feature employs a prefix tree (TRIE).
- Database Indexing: Databases utilize tree structures, often employing B trees for efficient indexing.
- Comments on LinkedIn Posts: Comments are structured as child nodes beneath the post, analogous to a tree structure.
