Java:

numUnique returns the number of unique values the list Precondition: the list is not empty and is sorted from low to high. { your solution can assume this is true }

For full credit, your solution must go through the list exactly once. Your solution may not call any other functions.

Examples:

["abcdef"].numUnique() == 6

["aaabcd"].numUnique() == 4

["bccddee"].numUnique() == 4

["abcddd"].numUnique() == 4

["a"].numUnique() == 1

public int numUnique() {

//Fix this
