Write a method called longestSortedSequence that returns the length of the longest sorted sequence within a list of integers. For example, if a variable called list stores [1, 3, 5, 2, 9, 7, –3, 0, 42, 308, 17], then the call of list.longestSortedSequence() would return 4 because it is the length of the longest sorted sequence within this list (the sequence –3, 0, 42, 308 ). If the list is empty, your method should return 0. Notice that for a nonempty list the method will always return a value of at least 1 because any individual element constitutes a sorted sequence.
