LeetCode has become a staple platform for coding practice, especially for those preparing for technical interviews or honing their programming skills. To maximize the benefits of LeetCode, it's essential to approach it strategically and systematically. In this detailed guide, we'll explore various aspects of how to LeetCode properly, covering key practices, problem-solving strategies, and tips for efficient learning.

Understand The Purpose Of LeetCode

One thing you can do on LeetCode is answer interview questions and read other things that are connected to interviews. It's one of the best ways to prepare for code interviews right now.
There are a lot of real interview questions from Google, Amazon, Facebook, Microsoft, Apple, Quora, LinkedIn, Bloomberg, Uber, Goldman Sachs, Twitter, and other well-known tech companies.
LeetCode serves multiple purposes, primarily centered around improving coding skills and preparing for technical interviews. Understanding the specific goals you aim to achieve will guide your approach to using the platform.
LeetCode offers a vast array of coding challenges, ranging from easy to hard. Engaging with these problems regularly enhances your problem-solving skills and familiarity with different algorithms and data structures.
Many tech companies use coding interviews, and LeetCode problems often mirror the types of challenges encountered in these interviews. Using LeetCode as a preparation tool helps you get accustomed to the problem-solving mindset required in technical interviews.

Create A Structured Learning Plan

Randomly picking problems without a plan might lead to a scattered learning experience. Create a structured plan to cover various topics and difficulty levels systematically.
Categorize problems based on topics such as arrays, strings, trees, dynamic programming, etc. This ensures a well-rounded understanding of different concepts.
Start with easier problems to build a strong foundation, then gradually move to more challenging ones. This progression allows you to develop both your understanding and problem-solving skills.

Quality Over Quantity

LeetCode is not about solving as many problems as possible but about understanding the underlying principles. Focus on quality solutions, ensuring you thoroughly understand the concepts behind each problem.
Before jumping into code, understand the underlying theory, algorithms, and data structures relevant to the problem. This knowledge will help you approach similar problems in the future.
After solving a problem, explore the Discuss section on LeetCode. It often contains valuable insights, alternative solutions, and discussions on different approaches.

Master Time Management

In a real interview scenario, time is often a crucial factor. Practice managing your time effectively when solving LeetCode problems to simulate interview conditions.
Allocate specific time limits for solving problems. This helps improve your ability to think under time constraints, a skill vital in technical interviews.
After completing a problem, analyze how well you managed your time. Identify areas for improvement and adjust your approach accordingly.
Unlocking LeetCode proficiencydemands a specific strategy. Initially, resist the urge to tackle problems independently. Surprising as it may sound, attempting any question on your own is a complete time-waster at this stage. Don't spend even five minutes on a problem; without the foundational knowledge, frustration and wheel-spinning are inevitable.
So, what's the approach? Simple. Here is how to LeetCode properly:
  • Consult "Grokking the Coding Interview" (no need to purchase; it's not worth it) and peruse their pattern list.
  • Select a pattern and head to LeetCode. Search for problems aligning with that pattern.
  • Review each problem under the chosen pattern, and directly delve into the solutions. Avoid spending even a second attempting to solve; it's counterproductive.
  • Deeply comprehend the solution. Take notes, research unfamiliar concepts, watch YouTube videos for insights, and explore the discussion section on LeetCode for alternative perspectives. Interact with the solution, tweak variables, etc. Essentially, grasp the solution as comprehensively as possible.
  • Move on to the next problem and repeat.
  • After repeating this process for a sufficient number of problems, you'll experience a lightbulb moment. Congratulations, you now understand how to solve this pattern!
  • Cycle back, choose a new pattern, and follow the same methodology.
By avoiding prolonged hours on individual problems, in just 1-3 weeks, you'll acquire a profound understanding of major patterns and common solutions. You'll develop the ability to discern how to deconstruct a problem into specific patterns, fostering a more efficient and accelerated learning journey.

LC should be the last step of your coding education before industry. Being able to write clean code is kinda assumed. It’s like a prerequisite for leetcode. Writing clean code is an art. Once you get it down, you can implement it everywhere for any code you write

Embrace Consistency

Consistency is key to improvement. Rather than sporadic intense sessions, aim for regular, shorter practice sessions to maintain momentum.

Dedicate a specific amount of time each day to LeetCode. Consistent daily practice reinforces learning and gradually builds expertise.
Periodically revisit problems you've solved to refresh your memory. This helps solidify your understanding and ensures retention over the long term.

Utilize Additional Resources

LeetCode is a valuable resource, but supplementing your learning with other materials can provide a more comprehensive understanding.
Explore additional resources such as coding books and online courses to deepen your knowledge of algorithms, data structures, and problem-solving strategies.
Join coding challenges on platforms like HackerRank or CodeSignal to diversify your problem-solving experience and expose yourself to different formats.

Build A Systematic Problem-Solving Approach

Having a structured approach to solving problems can significantly enhance your efficiency and effectiveness on LeetCode.
Understand the problem requirements, constraints, and examples before attempting to solve it. A clear understanding is crucial for devising the right approach.
Outline your approach before jumping into code. Consider different algorithms and choose the one that aligns with the problem requirements.

Leverage Debugging Techniques

Effective debugging is a skill that can save valuable time during both practice and real interviews.
Test your code incrementally rather than writing the entire solution at once. This helps identify and fix bugs early in the process.
Insert print statements strategically to trace the flow of your code. This technique assists in pinpointing errors and understanding how your code executes.

Join Coding Communities

Being part of coding communities can provide additional support, insights, and motivation.
Engage in discussions on LeetCode, join forums, or participate in coding communities to share your solutions, learn from others, and gain different perspectives.
Request and provide peer reviews for solutions. Constructive feedback from peers can offer valuable insights into alternative approaches or optimizations.

Track Progress And Celebrate Milestones

Keeping track of your progress and acknowledging milestones is essential for motivation.
LeetCode provides a profile section where you can track your progress and see statistics on problems solved by difficulty level. Use this feature to monitor your growth.
Celebrate small victories, such as solving a challenging problem or achieving a specific goal. Positive reinforcement contributes to a positive learning experience.
