The method removeDupes is intended to remove duplicates from array a, returning n, the number of elements in a after duplicates have been removed. For example, if array a has the values {4, 7, 11, 4, 9, 5, 11, 7, 3, 5} before removeDupes is called, then after duplicates are removed, a will be {4, 7, 11, 5, 9, 3} and 6 will be returned. Consider the following three implementations of RemoveDupes.
