Overcoming Technical Challenges: My Journey to Mastering Algorithms for Interviews
Understanding the Problem and Creating Solutions
When I first started my journey in learning algorithms, I faced numerous challenges. One of the biggest hurdles was understanding how to frame the problem and devise a solution. Unlike the popular misconception, learning algorithms is not just a matter of studying a textbook, but a process involving constant practice and improving over time.
To get a better grasp of algorithms, I took solid steps to ensure my foundation was strong. This included dedicating a significant amount of time to learning data structures, which are crucial for any algorithm developer. I carefully performed all the basic operations on databases such as ADD, UPDATE, DELETE, and traversing data structures. While I was initially interested in sorting algorithms, I found that I struggled with writing a proper Quick Sort implementation, even to this day. This indicates the importance of foundational knowledge before moving on to more complex algorithms.
The Journey to LeetCode and Self-Practice
Once I acquired a solid understanding of data structures, I shifted my focus towards solving problems on LeetCode. Videos on YouTube, such as those by iDeserve and Tushar Roy, provided a wealth of insights and various approaches to solving problems. By watching these tutorials, I gained valuable exposure to different problem-solving techniques.
I decided to take a hands-on approach and attempt to solve problems on my own, comparing my solutions with those of others to learn valuable techniques and tips. This practice was instrumental in refining my problem-solving skills and building confidence. With consistent practice, I gradually mastered a range of easy problems, enabling me to tackle problems from Competitive Programming Interview Handbook (CPiH) and Medium complexity problems effortlessly.
The CLRS and Confidence Building
The art of slicing through the level-up challenges lies not just in the constant practice but also in understanding the underlying architecture. If you aspire to truly master algorithms, consider consulting the Bible of Algorithms—CLRS (Introduction to Algorithms), which remains a unparalleled source of knowledge. However, I advice against referring to it as theBible of Algorithms, as this may create an unnecessary pressure to master it from the very beginning.
A critical step that helped boost my confidence was to write down my own version of algorithms without fear of making mistakes. Understanding that everyone makes blunders is liberating, and it allows one to focus on the learning process without the fear of failure. By coding an algorithm myself and then verifying it with references, I honed my problem-solving skills and built a stronger foundation in algorithm design.
Conclusion
Mastering algorithms is a continuous learning process. It requires dedication, perseverance, and a hands-on approach. By strengthening your foundational knowledge, solving problems on platforms like LeetCode, and using resources such as CLRS, you can significantly enhance your problem-solving abilities. Don’t let the fear of making mistakes deter you from the practice—it is a natural part of the learning journey.
