Dear Sahil , Thank you for your comprehensive tutorial on mastering Data Structures and Algorithms (DSA). Your breakdown of all DSA topics and provided links are incredibly valuable for learners like me. Your dedication to simplifying complex concepts is truly commendable.

first, study the theory of the topic, understand the concept well, just watching videos won't help. Try to solve questions on your own, if you are not able to solve, then only watch the video.

How to watch striver or love babbar videos? Do we have to code simultaneously or just watch their videos and note down the logic or the code in our notebook. Please tell me the correct way to solve it and master dsa🤔🤔 Please Reply 😢😢😢😢🥹🥹

just watching the entire playlist won't help you much. First read the theory of a particular DSA topic (and make notes), solve easy questions of that topic on your own from leetcode. now, talking about the playlists, see the question which they are solving, try to solve on your own first, if you are not able to solve, then only watch the video. don't enter into tutorial hell.

dsa preparation or any kind of preparation is not based on mathematical calculations. you can't quatify your preparation, forget the number of hours you are putting, just do it everyday consistently, you will see results. preparation is something which can never get completed, there is always a scope of improving, learning and pushing yourself. the day when you will get your placement, that day you can think that your preparation has been completed.
