Objective
Today we're discussing scope.
The absolute difference between two integers, a and b, is written as |a - b|. The maximum absolute difference between two integers in a set of positive integers, elements, is the largest absolute difference between any two integers in elements.
The Difference class is started for you in the editor. It has a private integer array (elements) for storing N non-negative integers, and a public integer (maximumDifference) for storing the maximum absolute difference.
Task
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 N and stores it in the maximumDifference instance variable.
Input Format
You are not responsible for reading any input from stdin. The locked Solution class in your editor reads in 2 lines of input; the first line contains elements, and the second line describes the elements array.
Output Format
You are not responsible for printing any output; the Solution class will print the value of the maximumDifference instance variable.
