//mistaken in for loop

for(int i = k; i < n; i++){
sum += nums[i];
sum -= nums[i-k];
maxSum = Math.max(maxSum, sum);
}

[MbuthiMungai]

Mistake in the loop

Should be:

sum += nums[i]
sum -= nums[i - k]

[AkshatMajila]

Error at 3:38, += and -= should be interchanged

1:22 . I found the way which is more understandable for me.. can I know is this something you created or it's available publicly. If it's available for other algorithms where can I find them .. if it's created by you can you also create such statements for other algorithms

[avinavkashyap]

nicely explained Ashish Bhaiya.
Looking for other videos.
Also please make a video on what all thinks should go on inour mind while solving a particular problem.HOW can we utilise your
300 PATTERN PROBLM to the best of our ability.

The contestant from Hangzhou has played the video at double speed.

The space complexity for the dynamic sliding window question should be O(s)

[shashikumar]

it should be
sum=sum-nums[i-k]+nums[i];
maxSum=Math.max(sum, maxSum);

[jikhjbjkl]

isst a hashmap better for the second problem since you can just put the left pointer to the value of the duplicate +1?

[MANIREDDYGAJU]

why didn't you make a video on the hashmap pattern, please make it sir.

[rohitmantri]

thanks bhai as many pointed, java code for fixed mein mistake hain, dhang se dekh liyo bhai. thoda phati 5 10 mins tak mera :D

[xavier]

Video is just explaining the technique. But as a daily DSA coder I won't support it. You has to solve tough questions for each technique

[JDK_]

Also make videos on que related to maths/ number theory

[sandeepvaishnav]

3:38 mistake in add and remove element in window

[AaishanAhmad]

good explaination and scripts but why are you talking like robot

[Syntax-scribe-jsx]

Galat kyu pdhate ho bhai ki jo pehli brr sikhe uska concept hi bigd jaaye..

For loop me mistakes kiye ho...

[GamingId-vq]

i dont understand your explanation of code dont know why as it feels like you are just reading it not teaching it.
