31:28 One more big optimization is possible in the longest subarray solution. if (arr[r]>k) { r=r+1; l=r; sum=0} Here if a number itself is greater than 'k' then no subarray with that element can be a valid substring. So, we can move both left and right pointers to the next element (i.e. arr[r+1])
@antor.morsalinАй бұрын
while optimizing, you kinda have to expect the input that is the most time consuming.

Hi Striver, I'm not sure if this comment will reach you or not, but I just want to say one thing: I've been watching your videos for more than a year now and have covered a huge part of the graph and dynamic programming playlists. Whenever I watch your videos, I really fall in love with your teaching style, and of course, your smile, and sometimes your small jokes. I enjoy your videos, and it feels like you're not just my tutor; it feels like you're someone very close to me, teaching me with fun and pleasure. However, in your recent playlists, I totally miss that. It feels like you're not as friendly anymore; you're just a teacher like any other tutor. Whenever I watch videos from this playlist, sometimes I wonder what happened to you. Why are you so quiet now? Why don't you joke around anymore? After all, I love your work; it's just my opinion.

Hi, Thanks for the video first of all 😊, but at time 12:28, we can't break from the loop (as you did in else condition) as array can have negative elements further which will reduce sum and it can bring sum to less than or equal to k. That else condition is fine only when we don't have negative elements in the array. At 21:05, we don't need the if condition to check if sum

At 21:55, isn’t it important for the while loop to have one more condition i.e l

5:20 why no one is talking about the issue in the first problem , the first subarray isn't considered why? and no conditions given inside while loop why? Here is the Correct code int nums[] = new int[] {6,2,3,-1,-5,1,1}; int k = 3; int left = 0; int right = 0; int sum = 0; int maxSum = Integer.MIN_VALUE; while(right
@sultan_30064 ай бұрын
I was also wondering why no one has commented on that part!
@prasannasahoo08063 ай бұрын
we will calculate the sum for the first subarray also and we later compare it with the upcoming subarrays sum . hope I made it clear
@purushottam1082 ай бұрын
before going to loop we can put maxSum = sum it also work fine: #include using namespace std; int main(){ int k = 2; vectorarr = {100,-2,1,-7,-1,10}; int sum = 0; int maxsum = INT_MIN; for (int i = 0; i < arr.size(); i++)sum = sum + arr[i]; int l = 0; int r = k-1; maxsum = sum;//so we dont miss the sum of first subarray while (r < arr.size()-1) { sum = sum - arr[l]; l++; r++; sum = sum + arr[r]; maxsum = max(maxsum,sum); } cout

Thankyou so much Striver for all you efforts throughout in delivering us so much valuable content. Any student / working professional can now be able to transition their career without paying money for courses. Would also like your insights on the point : While preparing for interviews most of the aspirants are going through the videos solely and solving the question after completely watching the video. And also are feeling lazy trying to solve the question on our own. What is the best way to complete any topic without being lazy and how should an aspirant approach any topic/playlist?

5:38 in this problem the sum of first subarray is not being considered, plz store it in a separate variable and put in maxi( ) as well, or after finding the sum using for loop assign max_sum= sum; in that case we dont need an extra variable

Optimization was so great 🥵 I never thought about improving 2n to n
@harshsheth55453 ай бұрын
It is important to note that Pattern 2 is applicable for positive numbers only. In your case itself if the array was [2,5,1,7,-5,10] instead of [2,5,1,7,10] your solution would be wrong.
@prasannasahoo08063 ай бұрын
can you explain how ?
@harshsheth55453 ай бұрын
@@prasannasahoo0806 sure. During the execution when L is at position 0 and R is at position 3, the subarray 2,5,1,7 gives the sum 15 which is greater than 14 so L will move to position 1. The new sub array now is 5,1,7. Then R moves to position 4 but L does not move back to position 0. So, the subarray 2,1,5,7,-5 which is a valid array but it is not checked in this method.

@SanjeevM-yc5uj4 ай бұрын
For the 3rd type where you find the number of subarrays satisfying the condition, can’t we just add an extra variable and check if the subarray is satisfying the equal condition and then increase the variable’s value accordingly. Like for example can’t we just include a variable called sub_array_count and then add 1 to it whenever sum = k inside the loop itself?
