Please keep making such videos!!our basics are getting stronger!

[@vishnulavudya3160]

You are really are underrated !

[@developer_save]

The way you explained, is outstanding just keep uploading videos . Its helping us a lot.

[@atulsolanki1735]

Great way to explain the problem and solution, to make it very simple and easy to understand. Thank you, Nikhil.

[@amitmandal5842]

As usual, you explanation is awesome.. Thanks you Nikhil..😊😊

[@suhas8882]

This code is not working in leetcode for all the test cases

[@mounikathalla3440]

great work Nikhil..... thank you for these tutorials....👏👌👌👌

[@pradyumnakhadanga1016]

I am watching all your videos, It is awesome.

[@IshaZaka]

great way of explaning

[@pradyumnakhadanga1016]

It can be improved protected static boolean isPollindrom(String str){ int left = 0; int right = str.length()-1; while(left

[@Radhe_Krishna2245]

Awesome explanation ❤

[@ash8726]

can you make a video on variable-size sliding window algorithm

[@nikoo28]

will try to make one on it. did you have a look at the sliding window algorithm already? kzbin.info/www/bejne/a2e3qXuDfJWknrM

[@prettymess21]

The code is not accepted by leetcode

[@nikoo28]

are you sure? I tried again, and it accepts. github.com/nikoo28/java-solutions/blob/master/src/main/java/leetcode/easy/ValidPalindrome.java

[@myosith4795]

we have to use palindrome concept in many cases ...

[@charlesopuoro5295]

Thanks always

[@nikoo28]

So nice of you

[@jcv178]

you didn't explain in the code how to ignore non-alphabetic characters

[@nikoo28]

i wanted to focus on the algorithm to check a palindrome. for your specific condition to check non-alphabetic characters, you can just add some if conditions. Also, it is not possible to account for every different problem. Some might have special symbols, some might allow numbers. Ideally, you should focus on understanding how the algorithm works...how to identify the palindrome...rest is just some decoration with if blocks and conditionals.

plz make more
