LEETCODE 1186: Maximum Subarray Sum With One Deletion | DP + Kadane’s Trick Explained
Question Link: https://leetcode.com/problems/maximum...
In this video, we break down the full intuition behind LeetCode 1186, where you must find the maximum subarray sum while being allowed to delete one element.
This problem is an advanced version of Kadane’s Algorithm and uses Dynamic Programming to track:
✔ Best subarray sum ending at each index
✔ Best subarray sum with one deletion
✔ How to combine both DP states
✔ Why this achieves an optimal O(n) time solution
✔ A clean step-by-step dry run to build intuition
This is a frequently asked interview problem and a must-know pattern for mastering DP on arrays.
