Can a beginner start with LeetCode?

Yes, a beginner can start with LeetCode, but it can be overwhelming without proper guidance and a structured approach. If you’re new to coding interviews or programming in general, it’s crucial to start with the basics and gradually build up your skills. Here’s a guide on how to effectively use LeetCode as a beginner and why considering an alternative like Grokking the Coding Interview from DesignGurus.io might be beneficial:

How to Start with LeetCode as a Beginner

1. Learn the Basics:

   • Before diving into LeetCode problems, ensure you have a good understanding of basic programming concepts such as loops, conditionals, functions, and data structures (arrays, linked lists, stacks, queues, hash tables).
   • Online courses, tutorials, and introductory programming books can help you build a strong foundation.

2. Start with Easy Problems:

   • Begin with easy-level problems to get comfortable with the LeetCode platform and the problem-solving process.
   • Focus on solving problems related to fundamental data structures and algorithms.

3. Understand Each Solution:

   • After solving a problem, review the solution and understand why it works. If you can’t solve a problem, read the solution provided and learn from it.
   • Take notes on the key concepts and techniques used.

4. Practice Regularly:

   • Consistency is key. Set a regular schedule for practicing problems on LeetCode.
   • Aim to solve a mix of problems, gradually increasing the difficulty as you become more comfortable.

5. Use LeetCode Discussions:

   • Participate in the LeetCode discussion forums to see how others approach problems. This can provide different perspectives and solutions.

6. Supplement with Other Resources:

   • Use additional resources like books (e.g., "Cracking the Coding Interview"), online courses, and tutorials to strengthen your understanding of algorithms and data structures.
