Medium difficulty problem. Congratulations on making it here!

Given an array of ints, find the maximum of each pair of elements and duplicate it. Thus, if the input array was {0, 4, 32, 10} the elements with index 0 and 1 in the output would both have the value 4, which is the greater of the input's first two elements. The elements in the output at indexes 2 and 3 would have the value 32, since that is the greater of 32 and 10. Precondition: a.length % 2 == 0, meaning that a will always have an even number of elements.

HINT: Math.max(int first, int second) will compute the larger of two numbers.
