 * Task description: Complete the Difference class by writing the following:
 *   * A class constructor that takes an array of integers as a parameter and saves it to the  __elements instance variable.
 *   * A computeDifference method that finds the maximum absolute difference between any 2 numbers in __elements and stores it in the maximumDifference instance variable.
