Sample Solution:-

C# Sharp Code:

using System;

// Namespace declaration
namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Displaying the output of the 'test' method with different integer inputs
            Console.WriteLine(test(123, 456)); // Output: False
            Console.WriteLine(test(12, 512));  // Output: True
            Console.WriteLine(test(7, 87));    // Output: True
            Console.WriteLine(test(12, 45));   // Output: False

            Console.ReadLine();               // Keeping the console window open
        }

        // Method to check if the last digits of two integers are equal in absolute value
        public static bool test(int x, int y)
        {
            // Using Math.Abs to get the absolute value of the last digit of each integer and comparing them
            // Returns true if the absolute value of the last digits of x and y are equal, otherwise returns false
            return Math.Abs(x % 10) == Math.Abs(y % 10);
        }
    }
}

Sample Output:

False
True
True
False
