## BJP3 Exercise 7.13: longestSortedSequence

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.

**Method problem:**
For this problem, you are supposed to write a Java method as described.
You should __not__ write a complete Java class;
just write the method(s) described in the problem statement.
