@@nikoo28 same opinion bro i have tried several channels but you are god in these... even though am using python am able to understand the algoritham from u and able to code from that

[@souvikmukherjee8419]

This Channel is a pure Gold ..... Found this few days back and really helpful

thanks for the lovely feedback :)

hey nikhil , all text based solution links are navigating to random page , can u pls check on that , it was working fine earlier

[@SrimathiN-sp5yr]

great work .Thanks for solving the problem from scratch

Happy to help

hello sir would you please make a video on subsequence using recursion for example if we have an arr = [1,2,3] output = ans = [[],1,2,3,[1,2][2,3],[1,3][1,2,3]]

Cool explanation. Thanks!

[@anutoshghosh7893]

In the two pointer approach, I did not understand one thing the ordering also has to be checked in a subsequence which is missing for the problem in the testcases, for instance here s = "acg" and t = "ahbgdc", they are considering s as a subsequence of t which should not be so, as the ordering is not maintained, although all elements are present from s in t. Please explain this once, because in your code as well the ordering part is not covered.

[@nikoo28]

acg is NOT a subsequence of abhgdc, the ordering of character changes

[@anutoshghosh7893]

Yes that was my query where are we taking care of this ordering as well in code even though acg is not a subsequence of ahbgdc, are we really taking care of it in code? If so how?

[@nikoo28]

@@anutoshghosh7893 in the last return statement. It will return a false with the test case you mentioned.

could u do the follow up question?

will do that soon, it got added recently after I posted the video.
