LeetCode 3835 – Count Subarrays With Cost Less Than or Equal to K | Sliding Window

Problem Link: https://leetcode.com/problems/count-s... In this video, we solve LeetCode 3835 – Count Subarrays With Cost Less Than or Equal to K using an efficient sliding window + prefix sum approach. This problem tests your understanding of two-pointer techniques, cost calculation optimization, and maintaining valid subarray conditions. We break down: The key intuition behind transforming the cost formula for fast computation How the sliding window ensures an optimal O(n) solution Step-by-step dry run to build clear understanding A clean, interview-ready implementation Time Complexity: O(n) Space Complexity: O(1) Let me know your feedback or which problem you'd like covered next!
