[@hoddybhaba6704]

Great explaination bro however you have a typo in space complexity i guess as it will be O(1)

[@nikoo28]

You are absolutely correct. The space complexity will be O(1). Thanks for pointing that out. :)

[@sureshkannan6313]

You're Such an understandable and clear explanation delivering instructor...Thank you.!!!

[@vipulaggarwal8518]

Your way to explain the approach and code is phenomenal. Thanks you Sir for providing great content 😊❤❤

[@pavanreddy3460]

You are explaining the problem clear and crisp.. keep doing the same... Thanks for sharing these videos

[@nikoo28]

So nice of you

[@NiteshMaurya1111]

your explaination is too good

[@ghanashrim2839]

I watched your house robber I problem explanation video first, and immediately fell in love with the way you explain the solutions. Your voice is soothing to hear as well and every word is clearly pronounced. I've had issues following other videos due to terrible audio quality and a monotonous tone of explanation. Thank you for making my life a bit easier with your solutions. Please solve all the problems from Sean Prashad's list 🙏

[@nikoo28]

Do you feel the audio problem in the recent videos too? All the ones I created House Robber 1? I know some of the earlier videos had a problem. Thanks for your kind words though :)

[@ghanashrim2839]

@@nikoo28 Oh no, I meant, I had problems following other KZbinr's videos. I haven't faced issues with your videos so far :)

[@geetikapathak]

very good explaination sir. thanks for your contribution

[@ujjwalsingh6889]

Great Explanation bro👌👌 I like your teaching method..........👍

[@saurabhc4278]

Awesome number line intuition !!

[@nikoo28]

Thank you!

[@Pankaj_singh15]

I was thinking of the same approach but couldn't find that last piece but after watching this video i got it, Thankyou this video was very helpful !

[@nikoo28]

glad it helped you

[@sanand6084]

Awesome as usual ! Can you please make a video which sort of gives a general approach to solve questions involving two pointers ?

[@nikoo28]

Great suggestion!

[@AnandL-yb2sg]

Thanks...

[@subee128]

Thank you

[@subhendumahanta3717]

if sum is less than the target, we have 2 options: increment left or decrement right. You have chosen to increment left. I can choose decrement right. Are the equivalent ?

[@nikoo28]

Is sum is less than target, and you decrement right…the sum will become even smaller..because the array is sorted. So you will get a smaller sum

[@jayeshpatil5757]

Thanks 20 June 19:02

friend, remove the apple logo in your video, put the known one not this shit Thanks for the explanation beside that
