1. How to take DSA Notes?

->Inputs and Outputs

->Edge Cases and corner cases

->Approach to solve the question

->Logic - formula, Diagram, Pseudo Code, Special Note eg- 2 Pointer,Greedy algo

->code - function with logic

->Time complexity

->dry run

3. How to approach DSA questions? Step-1 : Understand the problem.

Step-2 : Devise a strategy

->Write logic in paper.

1. Brute Force Solution

->Plan to solve question using brute force approach.

4. Efficient Solution

->Find out efficent method to solve this question. ->If efficient method is know try to write on paper.

6. Constraints - See that which algo works to solve the question by seeing the constraints

7. Edge Cases and Conrner cases

Step-3: Break down the problem if possible

Step-4: Write pseudo code and dry run the code(try to dry run edge cases /Corner cases)

Step-5: Implement the solution

->convert psedo code to code(C++, Java, Python)

Step-6: testing and debugging - Logical Mistake, Syntax Error, Spelling Mistake, Debugging, handling edge cases.

Step-7: Optimize and review
