Day 14: Scope

• Instructions:
  • Complete the difference class by writig the following:
    • A classconstructor 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
    • The difference class has a private integer array elements for storing N non-negative integers, and a public integer maximumDifference for storing the maximum absolute difference
      • The maximum absolute difference between two integers in a set of positive integers, elements, is the largest absolute difference |a - b| between any two integers, a and b, in __elements.
  • Constraints:
    • 1 <= N <= 10
    • 1 <= __elements[i] <= 100 where 0 <= i <= N-1
