[@arshdeep011]

underrated channel ,,your code and explanations are always very easy to understand makes a difficult question easy :)

after 2 hours your explaination helps me to understand the logic.Many many thanks from my heart

[@AbhishekKumar-zl1ho]

14:32 What if the element that has to be deleted is not on s[end]. for example, as on 8:21, end is on a, but we have to delete the b char from the set, how this 14:32 statement is taking care of this case.

[@Viralmems_xyz]

because we are not increment the start pointer so again check for start

[@Kamzmal]

I used to think that girls are not good at coding same as driving haha ... But you are amazing ... Really better than others ... your logics are straight forward and easy to understand ... and you use data structure ... Very nice ... Love from Delhi ...

[@googlebaba4045]

we can also do by using unorder set with less time complexity

[@Goku-dk4mr]

You explain better than so called driver😂😂

[@nagenHARP]

Good Explanation , all case are not passed not handling if character is in between of set

[@sanjusingh4842]

The char will be removed until it removes the duplicate element.. Try to run the code bro....

[@naveenkumarmaddala7830]

Thanks for the video. Can you share code on Java 8 for longest substring in a given string.

[@RAVIKUMAR-ef4wo]

good explanation thanks. This is short and crisp to the point. It could have been better if you could explain the intution behind to arrive at the solution.How a candidate can think if he sees similar questions without previously looking at the solution.

[@rahulgautam6387]

[@subhanOther]

const str = "abcabcbb"; let maxStr = ""; for (let i = 0; i < str.length; i++) { let longStr = ""; longStr += str[i]; for (let j = i + 1; j < str.length; j++) { if (longStr.includes(str[j])) break; longStr += str[j]; } if (longStr.length > maxStr.length) maxStr = longStr; } console.log("maxStr:", maxStr);

[@Idukhan-jj9kc]

V good 👍👌👏🙌

[@jayeshchaurasiya262]

Love uhh mam ❣️

[@lokeshthecodingguy7747]
