Subarray with given sum sliding window
WebModify our sliding Window solution to reach the Deque solution. Brute Force approach. Here, we are asked to find a subarray that satisfies the given condition. So try all non-empty subarrays. Check if a particular subarray sum is at least k. If so try to update the shortest possible length of subarray with sum >= K. For checking sum of a ...

Web21 Dec 2024 · With a sliding window, we start with our initial sub-array, which is that initial window. And then we slide that along our array, we remove that initial value and we add … Web22 Jul 2024 · This check is to make sure the sumvariable always has a sum of kelements. If window size is k, then all good. Then size becomes k+1when moving to next i. Now, sum has value of k+1elements, so you remove the first element from last windowfrom sumto make sumhave again sum of kelements. See image below for more clarity for k = 3.

Web8 Jun 2015 · We see that a subarray with max 10 must start after the index of 30 and end before the index of 40, so it has 1 possible left endpoint and 1 possible right endpoint, and there is 1*1 such array. We add 10*1*1 to the sum and pop the (1, 10) from the stack. The sum is now 10. 30 < 40, so a subarray with max 30 also cannot include this element.
