Suppose we have an array A 1....n of even number of elements. Suppose we pair up
(A[1], A[2), (A[3], A[4]),. . , (A[n – 1], A[n]). If each pair consists of 2 similar element, add
one copy to B and discard both otherwise. Recall that a majority is an element that occurs more
.....
than n/2 times. Select all the true statements.
A) If A has a majority m, then m must also be the majority of B.
B) If B has a majority m, then m must also be the majority of A.
C) If A has no majority, then B must also have no majority.
D) The size of B is at most n/2.
