Suppose we have an even number of objects, n, and are only allowed to test for equality. That is, we can
select two of the objects and tell, in unit time, if they are the same or not. Design an algorithm to test if
the set of n objects has any object which is a strictly majority element, that is strictly more than n/2 of
the objects are the same. If so, return the majority element.
Try to design an O(n log n) algorithm, using a divide and conquer approach. Justify why your algo-
rithm is correct. Also justify the upper bound on the run-time of your algorithm.
