I know the video is a bit long than other most visited YT videos for the same problem, but please jump on to timestamps for the approach you feel like learning. [Though all 5 approaches are incremental] ❤

Don’t get discouraged because of the views or subs! What you’re doing is absolutely correct and the perseverance will yield the results sooner or later!

[@ayaaniqbal3531]

Bro just watched your whole video and now i am your subscriber .Your Explanation is very Clear.

[@coderunner743]

Bro, I always try to watch your POTD video even if I missed it on the same day, because the extra points given by you are very useful.

[@dampdigits.69]

I was looking for videos that discussed cycle sort approach, and this video is the only one that I found

[@RohitKumar-hn6wj]

Nice explanation. efforts appreciated and hope you will be posting video regular.

[@mainakchanda7918]

Always know You have quality audience

[@fraserdab]

brooo dont be sad, i watch your videos everyday because i like watching maximum number of approaches in video format as it makes my life easier, i do spend quite some time on problems like reading multiple solutions but your videos make my life easier when I am lazy to read and understand solutions. Some cases in graphs i see people do bfs, dfs but i do see that you make sure that we also know what is the union find solution which is usually not there in most other videos

[@dhruvrawatt9]

Aryan sir the amount of effort you are putting in to give back to the community is just amazing . I know hardwork is a mere normal thing for you but then also thanks a lot for teaching us things in easiest way possible.

[@Jazzimus]

thanks a TON for covering all the approaches, i reached the second last approach myself but modifying the input array did seem a bit wrong. your way of explaining all possible approaches to a problem is intuitive and easy to understand.

[@UmmeKNeha]

I'm from Bangladesh. I watched the whole video and the approach is great. I learned new things. So pls don't get disheartened for views or reach.

[@priyanshu6173]

dont worry about the views and subs bro...your audience are only legendary people and thats why they are less in number

[@ManojKumarManuSai]
