Absolute Difference or Double It

Write a C# program to get the absolute value of the difference between two given numbers. Return double the absolute value of the difference if the first number is greater than the second number.

C# Sharp Exercises: Get the absolute value of the difference between two given numbers

Sample Solution:-

C# Sharp Code:

using System;
using System.Collections.Generic;

// This is the beginning of the Exercise20 class
public class Exercise20 {
    // This is the main method where the program execution starts
    static void Main(string[] args)
    {
        // Displaying the result of the 'result' method with different integer arguments
        Console.WriteLine(result(13, 40)); // Test case 1: 'a' < 'b', returns 'b - a'
        Console.WriteLine(result(50, 21)); // Test case 2: 'a' > 'b', returns '(a - b) * 2'
        Console.WriteLine(result(0, 23));  // Test case 3: 'a' < 'b', returns 'b - a'
    }

    // Method to calculate and return a result based on two integer inputs
    public static int result(int a, int b)
    {      
        if (a > b)
        {
            // If 'a' is greater than 'b', return the difference of 'a' and 'b' multiplied by 2
            return (a - b) * 2;
        }
        // If 'a' is not greater than 'b', return the difference of 'b' and 'a'
        return b - a;
    }
}

Sample Output:
