Check if One Integer 20 Less Than Another

Write a C# Sharp program to check three given integers and return true if one of them is 20 or more less than one of the others.

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Printing the results of the 'test' method with different integer values
            Console.WriteLine(test(11, 21, 31)); // Output: True (since the differences between all combinations of numbers are greater than or equal to 20)
            Console.WriteLine(test(11, 22, 31)); // Output: False (since the difference between 11 and 22 is less than 20)
            Console.WriteLine(test(10, 20, 15)); // Output: True (since the differences between all combinations of numbers are greater than or equal to 20)
            Console.ReadLine(); // Keeping the console window open
        }

        // Method to check if the absolute difference between any two numbers among x, y, and z is greater than or equal to 20
        public static bool test(int x, int y, int z)
        {
            // Returns true if the absolute differences between x and y, x and z, or y and z are all greater than or equal to 20
            return Math.Abs(x - y) >= 20 || Math.Abs(x - z) >= 20 || Math.Abs(y - z) >= 20;
        }
    }
}

Sample Output:

True
True
False

• Write a C# program to determine if any two numbers among three differ by 20 or more and the third is not in between them.
• Write a C# program to return true if one number is exactly 20 less or more than the average of the other two.
• Write a C# program to check if the difference between the largest and smallest number is at least 20.
• Write a C# program to return true if one of the numbers is both 20 less than one and 20 more than another.
