How to Study Algorithms Without a Computer Science Degree

Studying algorithms without a formal computer science background is entirely achievable with the right approach and resources. Here's a step-by-step guide to help you learn algorithms effectively:

1. Start with the Basics

   • Understand Fundamental Concepts: Begin by learning the basic concepts of programming and data structures such as arrays, linked lists, stacks, and queues.
   • Choose a Programming Language: Select a language you're comfortable with, like Python, Java, or C++, which are commonly used in algorithm studies.

2. Learn Core Data Structures and Algorithms

   • Data Structures: Dive into trees, graphs, hash tables, and heaps. Understand how they work and where they are used.
   • Algorithms: Study sorting algorithms (like quicksort, mergesort), searching algorithms (like binary search), and algorithmic paradigms like recursion and dynamic programming.
   • Big O Notation: Learn about time and space complexity to analyze the efficiency of algorithms.

3. Use Structured Learning Resources

   • Online Courses: Enroll in courses that offer systematic learning paths.

     • Grokking Data Structures & Algorithms for Coding Interviews: This course provides an in-depth understanding of essential data structures and algorithms with practical examples.
     • Grokking Algorithm Complexity and Big-O: Learn how to analyze algorithms efficiently, a crucial skill for understanding algorithm performance.

4. Practice Coding Problems

   • Solve Problems Regularly: Practice is key. Regularly solve coding problems to apply what you've learned.

   • Follow Coding Patterns: Recognize common patterns in coding questions to solve new problems more effectively.

     • Grokking the Coding Interview: Patterns for Coding Questions: This course helps you identify and understand common coding patterns used in interviews and real-world scenarios.

5. Read Educational Books and Blogs

   • Books: Consider reading books like "Introduction to Algorithms" by Cormen et al., which is a comprehensive resource.

   • Blogs: Follow educational blogs that explain algorithms in simple terms.

     • Mastering the 20 Coding Patterns: This blog post helps you grasp important coding patterns to enhance your problem-solving skills.

6. Watch Instructional Videos

   • Visual Learning: Videos can make complex concepts more digestible.

     • DesignGurus YouTube Channel: Explore videos like FAANG Coding Interview Patterns to gain insights into common patterns and techniques.

7. Join Online Communities

   • Forums and Groups: Participate in online forums like Stack Overflow or Reddit's r/learnprogramming to ask questions and learn from others.
   • Study Groups: Collaborate with peers who are also learning algorithms to share knowledge and resources.

8. Work on Projects

   • Practical Application: Implement algorithms in small projects or contribute to open-source projects to solidify your understanding.
   • Experimentation: Try modifying existing algorithms or creating your own to deepen your comprehension.

9. Understand Algorithm Complexity

   • Algorithm Analysis: Practice calculating the time and space complexity of algorithms you study.
   • Optimization Techniques: Learn how to optimize code for better performance.

10. Stay Consistent and Patient

    • Regular Study: Allocate dedicated time each day or week for studying algorithms.
    • Progress Tracking: Keep a journal of what you've learned to monitor your progress and stay motivated.

Conclusion

Learning algorithms without a computer science degree is a matter of dedication and using the right resources. By systematically studying and practicing, you can build a strong foundation in algorithms that will be valuable for coding interviews and your career in software development.
