Recursion - Array Questions (Theory + Code + Tips)

In this video, we cover #recursion questions that deal with arrays. This is an important video as it teaches you which technique to use when.

Things like passing arrays in arguments, returning arrays in recursion, creating local objects then sharing values, and more.

32:00 😁😁 "You've skipped the course I can't help you. Go watch the video properly" and then you says "ok, I'll repeat it."😂

[rakeshbabu]

Increase the frequency of dsa videos Kunal🙏🏻🙏🏻🥺🥺

Been going on and off studying CS because I was stuck on recursion. Used to stop studying in a matter of minutes since I couldn't understand anything related to it. Watched 3 videos of your RECURSION PLAYLIST and now recursion is a cakewalk to me. The best 3-4 hours I've ever invested, not even capping

[vedantyt]

Sometimes it's that aura of Kunal which makes us comfortable in getting the hard concepts easily.

[vittalmaheshwari]

Hey Kunal it has been a superb journey with you
I got a job offer from Microsoft
This is all because of your videos and your hardwork
Thank a lot Kunal
I will support you till my last breath

Insane teaching man
I was able to come up with my own solution in one line for linearsearch
return index == arr.length ? false : arr[index] == target || linearSearch(arr, index + 1, target);

If anyone watches the first time, i will say, please see all the videos carefully previously and watch the full video. Don't skip anyone

[jashhinger]

See you later byeee, at 58:50 that's was so funny🤣🤣🤣 love the way you teach..❤❤🚀🚀

[Helly_Patel]

Thanks for teaching us like no one did till now!! One small request, please make lectures on dynamic programming as well!!

[vikaskumarnitrr]

By the time I had subscribed to your channel, I always wait for your next upload just a little request, just increase the speed of uploading videos.
love you 3000 Kunal bhaiya

[projecthope]

Thanks Kunal, you're really a rare gem, I have understood recursion by just watching your contents

[chinmayatewari]

The level of dedication and the quality of content💯.... TONS OF RESPECT AND SUPPORT ❤

[ashisbhowmik]

You deserve a Big shoutout ❤️❤️❤️ for providing this type of quality education ..💯💯💯

[anirudhchakravarty]

Between rotated binary search and recursive binary search which approach do we use in an interview? Love this course btw. Would love to see sliding window, 2 pointer, trees and graph questions

[rishabhrawat]

you were right now i'm able to solve complex questions in my finger tips

[himanshu_]

Bhaiya please complete asap these course can't wait for more videos

[RakeshChanda]

hey kunal! 1:18:47 in dry run you have showed indices are stored in descending order but the output is in ascending order how is it possible??

[anithakavitha]

Someone explain Q5, I can't understand🤧🤧

[dipeshjadhav]
