Thank you so much for this videos! You help me get ready for my interview!

[lawanutech]

Thank you..Keep it up..More power to you👍

[shankardayal]

Thanks for sharing your idea.
But in interview I had seen that we had one rule
"Don't use any inbuilt methods".
Here we use predefined data structure set and its method.

[channelcuriousity]

Really i am stucked in solving geeks for geeks. After I solve your 100 basics problem. I have feelings to crack any questions.

[prakashranjan]

This will won't give correct o/p in case of str = "dvdf"; -> longest would be 'vdf'

[narendramodi]

try this one guys without any additional loops..
HashSet<Character> cha=new HashSet<>();
String Longest="";
String current="";
int j=0;
for(int i=0;i<s.length();)
{
char c=s.charAt(i);
if(cha.contains(c))
{
current="";
cha.clear();
i=++j;
}
else {
cha.add(c);
current+=c;
++i;
}

{
Longest=current;
}

}

As per the problem statement, for the string "abcdablsdh", isn't it expected to return "cdabls" as the result? However, it returns "ablsdh" because during the first iteration of the for-loop, once we reach the second "a" (index 4), we break there and continue with the result of the string. Is this what we are trying to achieve here? Your explanation would be helpful.

Sir to find longest substring - all substrings r of same length, none of them is large- abcd, bcda, cdab

[bharathkumard]

sir,
for taking user input what i need to do?

[harshitsaluja]

This code does not seems to work for "dvdf" the output comes as dv it should come as vdf

[shenth]

I haven't tested your code but I think it won't find the correct longest substring in every inputs. e.g. abcdaeb -> bcdae

[freeebeee]

Sir couldn't reach the telegram group assume the link might be expired

[dakshinrajavel]

It won't work for all String. For example, it won't work for ABADEXED

[maheshnaga]

Sir u r explaintion is very super I know theory of all java concept but coading section I can fail pls how start coding improvement

[amans]

Ok i understood this completely..
So can you please tell me whether the actual competitive programming is just like this or way harder than this?
Asking Just for some motivation.

[mtcqzim]

Thank you 😊. But why didn't you execute the program?

[saikrishnasaikrishna]

Sir you have to kept link of source code

[rohanchristopher]

Microsoft Interview Program : Input KKCCDFC out put should be KK2CC2D1F1C1, request you create video for this program

[srinivasand]

Longest substring with How to change the existing code sir

[uttamdey]

Hi you are doing a great work really thank you for all these effors from your side.

Wanted to ask I was trying with different combination of Strings for eg:-

"abacdab" -> the output for this should be cdab but if gives acd. The idea of removing the set and emptying the string inside the loop needs to be modified a bit.
