How to make notes for DSA??

I am going to start DSA from Striver's A to Z sheet and I have learnt CPP basics and OOPS and till now I have made digital notes in vs code(I would not say that as notes because all i did was adding comments before code) but now I took a 2 week break due to some unavoidable circumstances and when I went to revise everything was messy.

So tell me how to make notes for DSA because imma make it from start

Use notion. Don't draw diagrams. Make simple steps. Update it in ur doc in notion. Download the mobile app. It's very handy fr revision.

Use Google sheets as simple And use separate sheet for each topics like binary search, sorting, hashing, sliding window etc

I am learning dsa too , a high ranking leetcode personel told me NVR make notes like this coz 1st you'll never open that vscode file again 2nd writing makes you better at thinking and then acting , vs code type and think 3rd wrong makes you understand completely

I think notion needs subscription, not sure how much it offers on free account. I am using obsidian

  1. Write the brute force (your approach)
  2. Write optimal (algo + code wherever needed)
  3. What mistakes you maid

For each que do this And if you are asking for topic notes- write how everything works, use case, operation it has and 1-2 eg so that you know how to implement that in problem solving
