Tips for Note Making in DSA

Introduction

• Presenter: Fraz
• Purpose of Video: Provide tips on making effective notes for DSA (Data Structures and Algorithms)
• Emphasis: Watch the complete video for comprehensive understanding

Common Problems in Learning DSA

• Study from multiple resources
  • Different styles and presentation of algorithms and code
• Beginners face difficulties in recalling algorithms and understanding different coding styles
• Importance of making concise and easy-to-revise notes

Key Strategies for Effective Note Making

• Understanding Over Memorization:
  • Understand the algorithm fully rather than cramming it
  • Use multiple references, ask seniors and friends

Two Ways to Maintain Notes

1. Notebook (Hard Copy):
   • Useful for revising during boring lectures
   • Handy for college students where using laptops might not be feasible
2. Soft Copy (Digital Notes):
   • Store on PC; create folders for different topics (e.g., Dynamic Programming, Graphs, Segment Tree)
   • Include only new and important learnings to keep notes concise

Example of Note Organization

• Multi-source BFS:
  • Include code from a specific question tackled
  • Mention points/thoughts that came to mind while solving
  • Highlight unique use cases or insights

Four Important Tips for Note Making

1. Code Inclusion:
   • Write the code for new and unique algorithms or data structures
   • Include complexities (time and space)
2. Comments:
   • Describe your understanding, examples, and references
   • Helps recall the rationale behind specific parts of the code
3. Example Questions:
   • Attach specific example questions (from platforms like Codeforces, Leetcode) solved using the algorithm
   • Highlights practical application and understanding
4. Regular Revision:
   • Go through notes once a month to keep concepts fresh
   • Spend less time revising compared to initial learning, but still necessary

Addressing Common Concerns

• **On Remembering vs. Learning Questions: **
  • Focus on learning problem-solving techniques rather than just memorizing questions
  • Develop problem-solving skills by understanding applicable algorithms

Additional Resources

• Coding Ninjas Courses:
  • Offer systematic DSA courses in multiple languages (C++, Java, Python)
  • Provide assignments, questions, TA support
  • Includes a handbook with key data structures and algorithms
  • Offer competitive programming and web development courses

Conclusion

• Follow these tips and techniques for effective note making
• Regular revision will boost confidence for interviews and placements
• Engage with the content by liking and commenting
• All the best for interviews and placements!
