Bro still waiting for your dynamic programming course I believe only you can make it easier for beginners to learn this compared to other resources available .Please increase the pace..

[@architpandey8172]

Hey Kunal Hope u are doin fine. Please bring Graph and DP series. We are aware that bringing such a quality content for free is hard but we really need it!!!!

[@rohitnandagawali1589]

we all are eagerly waiting for your Dynamic Programming series

[@Griffith_1802]

Wait for 2 years 😂😂

[@debjit2660]

We know you are very busy, but please complete the course, the faith we have on you after going through the course is unimaginable. Cannot learn from anyone else after watching your skills.

[@LordSarcasticVlogger]

Nahi padhaega vo…usse paisa chaiye

[@Bunny-lq2ic]

Please bring Graphs and DP videos. Placement season is here and we really need it. Thank you!

[@user-bf7yz3qd2i]

isko nhi aata dsa , pehle khud pdhega aur bekar ki video bna dega, kisi aur se padh le bhai kyon apna time waste kr rha.

​@@user-bf7yz3qd2ichannel batao bhai java + dsa keliye

[@user-qx8tp1fe9d]

As the countdown to the end of my placement ticks closer with just three months left, I've been relying heavily on this playlist. It's been incredibly helpful, and I've found it so engaging that I've struggled to follow any other courses. Every time I try, it just reminds me of how fantastic this free course is. I understand that creating quality content takes time, but the anticipation for new videos is high. It's disappointing when a course isn't completed as promised, especially when it's been so valuable to us, especially with companies coming to our college to hire us in three months. Hoping to see it completed soon!

[@083charanpreetsingh7]

How much time it took to u to complete the course till here

But will surely wait for your videos on DP and Graphs. Thank you for all your efforts. Kudos to your work❤️.

Waiting for graph and dp series.... 😊

[@akshaya3264]

When will you complete This series atlist notify us about your plan for this series❤❤

[@sufiserious798]

There is a case where both the violation nodes are adjacent to each other in the inorder traversal. In this case, the second violation gets skipped and the second node reference variable stays null, resulting in compile time error. To resolve that, you can create an extra reference variable as 'adjacent' or 'possibleSecond' and whenever you find the first violation node, make sure that you record the current node in the extra variable. Later when swapping the values, if we find that the 'second' reference variable is null then we can just assign the 'possibleSecond' node reference to it and the case will be handled.

[@sahzadhussain12e46]

[@kartikverma6988]

🎉🎉🎉

[@aaabb-ww8dp]

I think Graphs, additional topics (sliding window, tries, kadane's algorithm) heaps questions will be better first than dynamic programming since dynamic programming is rarely asked while those others are essential for interviews
