Complete the getUniques and getDupes methods in the UniquesDupes class. Uniques are values that occur in the original list at least once. Duplicates are values that occur in the original list more than once.

Use the String split method to seperate the string. input.split(" ") returns a string array where the original input string has been seperated by spaces. For example, "a b cd e".split(" ") returns a string array containing {"a", "b", "cd", "e"}.

Sample Output

Original   : a b c d e f a c e a e

Uniques    : [a, b, c, d, e, f]

Duplicates : [a, c, e]
