Problem 3, Maximum Subarray Sum The Maximum Subarray Sum problem is the task of finding the contiguous subarray with largest sum in a given array of integers. Each number in the array could be positive, negative, or zero. For example: Given the array [-2, 1, -3, 4, -1, 2, 1, -5, 4] the solution would be [4,-1,2, 1] with a sum of 6. (a) (b) Give a brute force solution for this problem with complexity of O(n²). Give a divide and conquer solution for this problem with complexity O(n logn).

Problem 3, Maximum Subarray Sum The Maximum Subarray Sum problem is the task of finding the contiguous subarray with largest sum in a given array of integers. Each number in the array could be positive, negative, or zero. For example: Given the array [-2, 1, −3, 4, −1, 2, 1, −5, 4] the solution would be [4,-1,2, 1] with a sum of 6. (a) (b) Give a brute force solution for this problem with complexity of O(n²). Give a divide and conquer solution for this problem with complexity O(n logn).
