Author: Whitaker Brand (on 2016/09/08)

Write a method longestSortedSequence that returns the length of the longest sorted sequence within a list of integers. For example, if a variable called list stores the following sequence of values:

       
[1, 3, 5, 2, 9, 7, -3, 0, 42, 308, 17]

then the call: list.longestSortedSequence() would return the value 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 non-empty list the method will always return a value of at least 1 because any individual element constitutes a sorted sequence.

Assume you are adding to the ArrayIntList class with following fields:

public class ArrayIntList {
    private int[] elementData;
    private int size;

    // your code goes here
}
