Kadane’s algorithm finds the maximum sum of a contiguous, nonempty subarray in O(n) time and O(1) extra space. The key is to decide at each element whether to extend the current subarray or start a new one. For example, for an array, a = [-2, -4, 4, -2, -1, 1, 5, -7] A contiguous subarray = [4, -2, -1, 1, 5] gives the maximum sum of 7. Application Maximum sum… Read More »Kadane’s Algorithm: Maximum Subarray Sum in Python, Java and C++
