A curated collection of foundational programming problems with full algorithmic explanations and reusable helper functions, solved using JavaScript.
Tired of learning syntax for every new language? This project is built on the core belief that fundamental programming logic transcends language boundaries. By mastering the concepts here in JavaScript, you'll gain a universal understanding that makes coding effectively in any language intuitive and accessible.
This repository aims to:
- Practice clean and optimized code: See real-world applications of best practices.
- Explain the logic behind solutions for long-term retention: Don't just copy-paste; truly understand why and how algorithms work through detailed explanations.
- Build a strong base for Data Structures & Algorithms (DSA) and technical interviews: Sharpen your problem-solving skills crucial for career growth.
- Serve as a personal logic library and teaching tool: A go-to resource for revisiting core concepts or explaining them to others.
This repository is structured to guide you through programming challenges categorized by difficulty, with a unique emphasis on the underlying logic.
/easy/→ Fundamental problems to build confidence./medium/→ Intermediate challenges to deepen your understanding./hard/→ Advanced problems to push your problem-solving limits./data-structures-basics/→ Essential implementations of classic data structures./logic-notes/→ Your key to mastery! This folder mirrors the problem structure and contains detailed Markdown (.md) files explaining the step-by-step logic and multiple approaches for each problem.
Inside, you'll find:
- A
.jsfile containing 5-6 different solutions to the problem, showcasing various logical approaches or optimizations. - A corresponding
.mdfile in thelogic-notesdirectory, providing an in-depth, conceptual breakdown of the problem's solution.
Ready to dive in? Follow these simple steps:
-
Clone the repository:
git clone https://github.com/0xrootAnon/core-programming-logic
-
Explore a problem: Navigate to any difficulty folder (e.g.,
/easy/) and select a problem file (e.g.,exampleProblem.js). -
Understand the Logic (Recommended First!): Crucially, open the corresponding Markdown file in
/logic-notes/(e.g.,/logic-notes/easy/numbers/exampleProblem.md) to read the detailed algorithmic explanation. -
Analyze the Solutions: Review the
.jsfile to see how the explained logic is implemented through multiple different code solutions. -
Practice & Apply: Try solving the problem yourself, then compare your solution, or even try implementing the logic in another programming language!
