Maximum subarray problem is to find a contiguous subarray with the largest sum, given an array of numbers. Given N numbers from array A[1N] with indices 1ijN, the sum k=ijA[k] is the largest possible. For example, given the array of values [2,1,3,4,1,2,1,5,4], the contiguous subarray [4,1,2,1] has the largest sum 6. Design two algorithms to solve the Maximum subarray problem. The second algorithmic design is an improved version to the first (initial) algorithm proposed. (a) Design a brute force (the first) algorithm to solve the maximum subarry problem. - Describe the design rationale of the algorithm. - Use pseudocode to layout the design - Implement the algorithm in Java (b) Design an improved (the second) algorithm to solve the maximum subarry problem. - Describe the design rationale of the algorithm. - Use pseudocode to layout the design - Implement the algorithm in Java (c) Run experiments with input sizes doubled each time on both algorithms, fairly with same inputs of the same size, to establish their running time model using power law. (d) Conclude on your findings
