1. For this problem consider the Maximum problem stated below.
Маximum
Input: A sequence of n integers A= (a1,a2,., an).
Output: aj e A such that a; 2aj for all aj e A.
a) Using pseudocode state an algorithm that solves the Maximum problem using a
loop.
b) Identify the loop invariant for the loop in your algorithm that will help you prove
your algorithm is correct. That is, state the loop invariant as a proposition of the
kind "After iteration i of the loop...".
c) Using induction prove that your loop invariant holds for each iteration i.
d) Using the loop invariant show that your algorithm is correct.
