Whenever the running sum dropped below zero, we discarded it because a negative sum always reduces the next number. Multiplication changes the game entirely: Because of this, the minimum product ending at the previous index can become … Continue reading Master Maximum Product Subarray (LeetCode 152): Modified Kadane’s | Day 8 of 180
