Video is good but again not gonna like and share your video otherwise competition will increase as the video will reach others as well

I have done dsa in java but for your approach and explanation I will watch your video and implement code in java with your approach 🙂

[@mohit7717]

Great Explanation ... Thanks a lot ... ike unordered map approach ... that insane

[@rajrajesh1669]

Luv u bro❣️ u always have my back.😢 I was able to think of approach 3 by myself but I missed That optimization that you told "There is no point in returning exceeded height" and because of that I thought that approach will give TLE. I'll pause the video and try to implement the solution then come back to watch the 4th approach.

Nice explaination 👍👍

[@mdsajidanwar6416]

How can we solve Approach 1 when there is no unique nodes? Can someone explain

[@SlapB0X]

Nodes will always be unique, the node->val can repeat. Hence, you can use an ordered map in C++ , to store the TreeNodes* as key and whatever value you want

[@curlyoreki]

can you also link the code

@ Aryan Mittal Bhaiya I am hopeless right now...not able to solve this despite solving over 350 questions on lc.Same happens in contest too..Able to solve only 2 always and get stuck on 3rd one....3rd year is about to start..Only 1 year left in placements...... please suggest some tips😓😭

[@mohit7717]

Don't hopeloess bro your are doing good but keep doing consistently. Keep solving atleast one problem daily.

[@yagniktalaviya2146]

Buddy, make an excel for c and d for last 200 contests and try the problems, not able to solve, look up the topics, still not, solution. You will eventually start to get it!!

I have 5 years of experience. I have solved 600+ problems on LC. I was not able to think of this approach. So you have long way to go my friend. Dont sweat it out.

I have subscribed your channel but the notification was personalized. I was checking notifications for todays problem but yt algo was not pushing. So I go to my subscriptions and changed notification to all of your channel. Sometimes I do daily problem by myself and when I fails, I remains confident that today Im gonna learn a new aproach by your vides. I bet there is no one who will not understand the problem by your teaching.. Thanks for making my life confident and easier 🙂.
