WebDynamic Programming - Maximum Subarray Problem. Objective: The maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers that has the largest sum. int [] A = {−2, 1, −3, 4, −1, 2, 1, −5, 4}; Output: contiguous subarray with the largest sum is 4, −1, 2, 1, with sum 6. WebI changed the base of the recursive algorithm, but that doesn't change the crossover point. 4.1-4 Currently the implementation already supports empty array, but it returns (-1, -1, -float('inf')) , we can change it to an empty array.
