Kadane's Algorithm : Maximum Subarray Sum in an Array
In this video, we will solve the problem of finding the maximum subarray sum in an array using Kadane's Algorithm. This is a fundamental problem in dynamic programming and is commonly asked in coding interviews. We will walk through an efficient approach that finds the maximum sum of any contiguous subarray in linear time. A C++ implementation will be provided to help you understand the concept and application of Kadane's Algorithm. This tutorial is part of the Striver DSA Sheet series, designed to sharpen your skills for competitive programming and technical interviews.
