Question

Given an integer array [A], efficiently find a descending sorted triplet such that: A[i]> A[i]> A[k] and 0 <=i<j <k <n, where n is the array size. For example,

Input: A[] = {9, 1, 6, 7, 3, 4, 5)

Output: Any one of the following triplets:

(9, 7,5)

(9, 7, 4)

(9, 7, 3)

(9, 6, 5)

(9, 6, 4)

(9, 6, 3)

a) Design a brute-force algorithm to solve this problem complexity of your solution

b) Design a more efficient algorithm to do the same task with less complexity and analyse the complexity of your solution.

c) Develop a python code to implement your efficient algorithm. depend on the correctness of the code, indentation, comments, test-case]

d) Prepare a brief report (250 words) comparing the two algorithms
