Day 14 Scope Hackerrank Solution in C++ | 30 Days of Code

Write a Program to Day 14 Scope Hackerrank Solution in C++. Hackerrank Scope Solution in C++. Day 14 Hackerrank Solution in C++. 30 Days of Code Scope Solutio. 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.

Day 14 Scope Hackerrank Solution in C++

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.


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.

Input Format

You are not responsible for reading any input from stdin. The locked Solution class in the editor reads in 2 lines of input. The first line contains N, the size of the elements array. The second line has N space-separated integers that describe the _elements array.


1 <= N <= 10
1 <= _elements[i] <= 100, where 0 <= i <=N - 1

Output Format

You are not responsible for printing any output; the Solution class will print the value of the maximumDifference instance variable.

Sample Input

STDIN Function

----- --------
3 __elements[] size N = 3
1 2 5 __elements = [1, 2, 5]

Sample Output



The scope of the _elements array and maximumDifference integer is the entire class instance. The class constructor saves the argument passed to the constructor as the _elements instance variable (where the computeDifference method can access it).

To find the maximum difference, computeDifference checks each element in the array and finds the maximum difference between any 2 elements: |1 - 2| = 1.

|1 - 5| = 4
|2 - 5| = 3

The maximum of these differences is 4, so it saves the value 4 as the maximumDifference instance variable. The locked stub code in the editor then prints the value stored as maximumDifference, which is 4.

            for (int j = 0; j < this->elements.size(); j++) 
                int absolute = abs(elements[i] - elements[j]);
                if (absolute > maximum) maximum = absolute;

        maximumDifference = maximum;
