BJP3 Exercise 7.13: longestSortedSequence

Added by: Whitaker Brand on 2013/04/01

Write a method named longestSortedSequence that accepts an array of integers as a parameter and that returns the length of the longest sorted (nondecreasing) sequence of integers in the array. For example, if a variable named array stores the following values:

int[] array = {3, 8, 10, 1, 9, 14, -3, 0, 14, 207, 56, 98, 12};

then the call of longestSortedSequence(array) should return 4 because the longest sorted sequence in the array has four values in it (the sequence -3, 0, 14, 207). Notice that sorted means nondecreasing, which means that the sequence could contain duplicates. For example, if the array stores the following values:

int[] array2 = {17, 42, 3, 5, 5, 5, 8, 2, 4, 6, 1, 19}

Then the method would return 5 for the length of the longest sequence (the sequence 3, 5, 5, 5, 8). Your method should return 0 if passed an empty array.
