*corrections*
*Initialize the msum to Integer.MIN_VALUE because all the wsum may be negative and in that case the msum will never be updated by the wsum.*

and

in second method, *maxSum = Math.max(maxSum, windowSum);
// added as a part of correction*

public static int A, int k) {
int windowSum = 0, maxSum = Integer.MIN_VALUE;
for (int i = 0; i < k; i++) {
windowSum += A[i];
}
*maxSum = Math.max(maxSum, windowSum);
// added as a part of correction*
for (int windowEndIndex = k; windowEndIndex < A.length; windowEndIndex++) {
windowSum += A[windowEndIndex] - A[windowEndIndex - k];
maxSum = Math.max(maxSum, windowSum);
}
return maxSum;
}

Explaining tough problems with a dry explanation is easy and commonplace. Your work is brilliant because it makes tough problems seem easy to solve!

I don't have an interview but was looking for a solution to a sliding window problem for my program, I thank you for your unique style in teaching It's very clear and easy, thank you.

I've been Stuck in this particular problem . Have watched many videos. But I can't understand their way of explanation . But you just Nailed it. Keep doing videos in some special questions asked by huge product based companies please.

[saravananj]

trust me this the best video u can find in youtube in this topic

[manshibachhan]

Please continue posting of such types of videos it is really very helpful ❤

[vaibhavikhachane]

In first for loop you need to write "maxSum =windowSum" because if we are getting the max in our first for loop than we need to return that maxSum;

Happily subscribed. Great to see you discussing the patterns. Keep them coming.
One request though, please site some problems that can be solved using the pattern. It will be an exercise to the viewer and will complete the learning cycle
