Thanks a lot for the clean explanation, it was a tough one, would it be possible to explain more BinaryTree examples from Leetcode?

[@itsdineshvaryani]

@@kananmehdizade5171 sure

Best series for DS & Algo. I am also 10 yrs java exp guy. Was looking for DS & Algo free course over KZbin with java implementation and found this. Hats Off To You Man..Excellent Work. GOD BLESS YOU :)

[@itsdineshvaryani]

Thanks !!!

[@vipulberiwal]

Thanks for the great explanation and providing reasoning behind why we are doing that.

[@mohnishpwr10]

Good learning experience so far. DSA has always been mysterious and tough for me. Looks like I will be able to do something about dsa after watching these videos.

[@itsdineshvaryani]

Thanks for such kind words !!!

[@KCTsangKen]

Thank you Sir, I really appreciate this video (and many other of your videos, too), and you step-by-step don't-rush approach is just great. Although I can understand the logic, my problem is that I often forget a couple of key pieces in the algorithms. The animation really helps me memorizing them. Haven't checked out all your videos yet but I hope you can make more animation videos on more advanced algorithms such as Kosaraju or Aho-Corasick, etc.

[@itsdineshvaryani]

Will add after pending topics !!!

Nice explanation sir. I learned how to traverse binary tree through your video series. Many thanks.

[@itsdineshvaryani]

Welcome. I would request you to please share the course with your friends and colleagues. It would help the channel to grow and motivate me to add more videos.

[@suseelkumarannamraju]

@@itsdineshvaryani Yes sir. I have passed on to my colleagues

[@itsdineshvaryani]

Thank you so much for the support !!!

[@apsey2162]

understanding this logic was quite tough, was it a hard level problem and do we need to make such logics and code while in dsa???

[@itsdineshvaryani]

Absolutely !!!

[@victorokpube5501]

thank so much for the explanation.what is the difference between pop and pull.and should the pull method be used in a stack instead of the pop.

[@itsdineshvaryani]

Java stack usually has pop method ... use that !!!

Dinesh sir i think the programme time complexity is o(n^2) please reply sir

Nope !!!

very nice explanations...your videos are superb...

Thanks !!!

[@ascar66]

Thank you sir! Great explanation

[@vaibhav9876]

Do we have to think such logics on our own??...as it seems quite tricky when i was trying to made the logic before watching the video

[@itsdineshvaryani]

Yes ... You hv to practice and make such concepts !!!

[@rishabsud7535]

can someone please explain about the time and space complexity of recursive vs iterative approach in this scenario? which one is better?

[@AshishYadav-ey2vv]

sir how you come up with such a difficult algorithm . How your mind works? Our mind will never be able think that deep

[@itsdineshvaryani]

It comes with practice ...

[@mrunaligaikwad1953]

Why is pop() method not used here, i believe poll() is generally used with a queue

[@itsdineshvaryani]

its actually pop method ... sorry for typo ... watch its next video for proper code

[@tusharkhandave374]

@@itsdineshvaryani but using pop is giving empty stack exception
