Kadane algorithm is the fastest and optimized algorithm of Maximum Sum Subarray problem. Maximum sum subarray is the contiguous subarray within a given one dimension array with the largest sum. This problem is one of the classical interview questions in IT companies like Google, Apple, Amazon, LinkedIn, Facebook, Microsoft, Uber, and many more. For example, for an array, a = [-2, -4, 4, -2, -1, 1, 5, -7] A contiguous… Read More »Kadane algorithm for Maximum sum subarray problem: Java, Python and C++ code of Kadane algorithm
