*Question*

(Mid Term, Marks = 10, Lesson No. 16)

Given a sequence [A_{1}, A_{2}, A_{3}, A_{4}]

- Order of A
_{1} = 10 x 100 - Order of A
_{2} = 100 x 5 - Order of A
_{3} = 5 x 50 - Order of A
_{4} = 20 x 50

Using the Brute force method compute the order of the product A

_{1}, A

_{2}, A

_{3}, A

_{4} in such a way that minimizes the total number of scalar multiplications.
