# What Approach Should I Follow to Learn DSA and Solve Problems as a Beginner?
As a beginner diving into the world of Data Structures and Algorithms (DSA), the journey can seem overwhelming. With countless resources, strategies, and opinions out there, it’s hard to know where to start. If you’re in this boat, you’re not alone! Many learners have the same questions and concerns. In this post, we're going to tackle some of the most common queries beginners have about learning DSA and provide a structured approach to help you succeed.
## 1. Where to Start?
The first step in your DSA journey is to familiarize yourself with the fundamental concepts and data structures. A solid understanding of the basics is crucial. You might want to begin with a beginner-friendly course or book that covers the foundational topics. Online platforms like Coursera, Udacity, or free resources like YouTube can be excellent starting points.
Additionally, reading introductory material or watching tutorials on basic data structures (arrays, linked lists, stacks, queues) and algorithms (sorting, searching) will set a strong foundation.
## 2. Should I Follow Sheets Like Neetcode150/Strikers?
Absolutely! Once you have a grasp of the basics, utilizing curated lists like Neetcode150 or Strivers can be incredibly beneficial. These resources highlight common problems and patterns that frequently appear in coding interviews.
However, before jumping into these sheets, ensure that you are somewhat familiar with the concepts. If you struggle with the patterns, take a step back and reinforce your foundational knowledge first.
## 3. What Should Be My Plan?
Your plan should be structured yet flexible. Here’s a suggested roadmap:
- **Week 1-2**: Focus on learning and revising the fundamental data structures and algorithms.
- **Week 3-4**: Start solving problems from Neetcode150. Break them down into categories (e.g., arrays, strings, etc.) and tackle a few problems from each category.
- **Ongoing**: As you progress, continuously revisit and practice different categories while challenging yourself with new problems.
## 4. How Many Questions Should I Do Every Day?
Quality over quantity! It’s better to solve a few problems deeply than to rush through many. Aim for 1-3 problems a day, depending on their complexity. Focus on understanding the problem, developing a solution, and analyzing its efficiency.
If you find a problem particularly challenging, spend time understanding the solution and the underlying patterns rather than moving on too quickly.
## 5. How Should I Make Notes from the New Topics/Algorithms/Approaches I Learn?
Effective note-taking can enhance your learning experience. Here are some tips:
- **Summarize Concepts**: Write concise summaries of new topics or algorithms.
- **Visual Aids**: Use diagrams or flowcharts to represent algorithms visually.
- **Examples**: Include example problems and solutions that illustrate the concepts.
- **Review Regularly**: Schedule time to go back through your notes to reinforce your learning.
## 6. How to Remember the Approaches?
To retain the approaches you learn, practice is key. Here are some techniques:
- **Active Recall**: After learning a new approach, try to recall it without looking at your notes.
- **Teach Others**: Explaining concepts to others can reinforce your understanding.
- **Regular Revision**: Set aside time to revisit previously learned topics.
## 7. How to Be Consistent?
Consistency is crucial in mastering DSA. Here are a few strategies:
- **Set a Routine**: Dedicate a specific time each day for practice.
- **Use a Tracker**: Keep a journal or use apps to track your progress.
- **Stay Motivated**: Join study groups or online forums to connect with others on the same journey.
## 8. Should I Learn Web Development Parallelly by Learning DSA?
This largely depends on your goals. If you aspire to become a web developer, learning web development alongside DSA can be beneficial. The two fields complement each other, as understanding algorithms can improve your coding skills, which will be useful in web development projects.
However, if DSA is your primary focus, consider prioritizing it first before delving into web development.
## 9. If I See the Solutions for the Questions I Can't Do and Do Again Without Looking at the Solution, Will This Approach Work?
Yes, this approach can work, especially if you’re struggling with a problem. Reviewing the solution can provide insights into different approaches and strategies. However, ensure that you attempt the problem again without looking at the solution afterward.
This technique of ‘learning from solutions’ can help you grasp new concepts, but aim to solve problems independently as much as possible to build your problem-solving skills.
## Conclusion
Learning DSA is a journey filled with challenges and rewards. By following a structured approach, staying consistent,
