Dear Kunal, The posterity will thank you for this service..nobody would have done this for free.each and every course that you have made is THE best and uncomparable. needless to say your code approach is a piece of art. This is coming from someone who is not from software background at all but is slowly getting confident at DSA. Cheers and God bless.❤

Sir, I have done 1:15:23 Question (First and last Element in different way) - First I found the floor no - Smallest no closest to target which is ( Return end) basically and end = end + 1, will give the first index, and similarly I found Ceiling - Largest no closest to target which is (return start) basically and start = start - 1 gives the last index. Also submitted on LeetCode.

But you havebeen giving a great lectures of DSA for giving free. Now I give lots of love from heart. Please consider KUNAL love from my heart to money. I think love is greater than money.

[@bhuvanachandra5121]

Some people are actually forgetting that we have to use an infinite array for Q5. In infinite array, there would be no out of bound error. Currently you are checking with finite array and that's why you are getting out of bound error. Just to clear your doubts that kunal also used an finite array in the example, also you'll definitely find the target number at one point of time if you use infinite array. So no out of bound errors

[@Thammudu_____]

Thank you

[@user-bk8wq1iq4n]

Thank u so much

[@limitXbreaker]

how can you say that we are going to find the target element in an infinite array. Say for example your target element is 2019312 but array does not contain instead it contains number greater than this and smaller than this then?

[@Shaheer-xs5os]

@@limitXbreaker If the problem is starting to find a number in the infinite array, then there must be one... else the loop will run infinitely and the question also understands this... but even if it does not exist then it will return -1. because we are not going much further than our target range... understand the solution first...

[@kunj8342]

​@@limitXbreakerbro we are doing binary search in chunks if target is not between start and end we will increase size of chunk and go ahead but if target is between start and end that u have said that u element smaller and greater than target so we will just apply binary search in that if target elemnt will exist u will find if not like 2019312 does mot exist so binary search will return -1 it means u don't find the target so target element does not exist in array and u will exit the method because if you have found the range in which the target elemnt exist then you will not move to next chunk or range if target is not found because if you move to next chunk target element is smaller than the start element so our condition will violate that target must be between start and end...

Take a bow Kunal!! I had tried solving about 15 - 30 binary search problems, but was still not able to figure out when and how to modify the while loop. Your explanations are the best by far of any KZbin tutorial I have seen. Thanks a lot for your efforts. 💯💯

I am not so good in English communication so I always try to learn by Hindi medium videos like CWH but when I started to watch your videos you just break my assumption and really really Enjoying your course. You just simplified every thing in such way that everyone can learn by basics. Love u Bro...

You are the best. I truly appreciate your time and effort in making all subjects easy to understand. Kunal, you are a fantastic teacher. I will highly recommend this course to anyone who struggles with coding. Thank you so much!

Thanks Kunal for developing problem solving skills , at this moment I can see myself not worrying about what to code but instead thinking of the logic and possibilities for the problem. A big THANKS

[@dhansbisht9433]

before this i was just aimlessly solving bs problems without even understanding what is going on but now i feel like i'm understanding it a lil more as each question passes. never felt this excitement while doing dsa questions lol thanks Kunal

[@tsdineshjai8565]

I just want to say this, may God bless you more Kunal, so that you can do more good things to the community. I have to admit this course is the best one available in the market.

The best DSA course on youtube I am watching this lecture on binary search after 2 months of gap no DSA in these two months and by just looking the questions I can generate the solution what would it be. Even I am able to derive the formula for infinite array search on my own. Thank you for the best course :)
