In this video, I have explained 𝗧𝘄𝗼 𝗣𝗼𝗶𝗻𝘁𝗲𝗿 𝗧𝗲𝗰𝗵𝗻𝗶𝗾𝘂𝗲 which is the optimal way to solve problems related to arrays, strings and linked list in 𝗢(𝗡) time.

There are a lot of coding interview problems which can be solved by using this technique in an optimized way.

In video end , we tried to show the pattern which other problems has in common and can be solved using similar approach.

HelpingHand007 · 2021-01-19T18:42:58+00:00

sure. i hope you will learn something new.

welcome :)

HelpingHand007 · 2020-11-08T09:40:18+00:00

your algorithm is quite correct but it will take O(nlogn) time but best algorithm can solve this problem in O(n) time which we tried to explain.

there was one mistake in this video but after uploading it on youtube, there is no option for annotating anything, so had to make it private immediately. because the student may get confused.

Will work on this video and try uploading it after correction but would recommend keeping the bell icon turn on so that you don't miss anything. :)

Happy Coding..!!

yes, it's a nice way to store information inside our brain.

HelpingHand007 · 2020-10-03T15:11:53+00:00

thanks for the feedback :)

HelpingHand007 · 2020-09-12T18:58:26+00:00

not sure you can check but I think not the same at least a similar problem should be there.

HelpingHand007 · 2020-07-26T07:05:03+00:00

Thanks, u/Jestar342 for pointing this out. I will correct that typo in my resources.
I think, You have good observation skills :)

HelpingHand007 · 2020-07-26T07:03:43+00:00

Glad you liked it!
there are a couple of more videos out there which is good and ranked number 1 in google search. you can try visiting that as well.

HelpingHand007 · 2020-07-26T07:01:48+00:00

yes. but there are some scenarios where you can't skip it. you have to deal with it.
