Create a public non-final class named Partitioner. Implement a public static method int partition(int[] values) that returns the input array of ints partitioned using the last array value as the pivot. All values smaller than the pivot should precede it in the array, and all values larger than or equal to should follow it. Your function should return the position of the pivot value. If the array is null or empty you should return 0. You will probably want to review the array partitioning algorithm presented in class. Note that we are asking you to partition based on the last value in the array, rather than the first. However, you can address this difference with a small adjustment before you begin.

Write a program called assignment3 (saved in a file assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b.c. it is a simple but very e↵ective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the “larger” integer is replaced by the di↵erence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.
