Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {               
            // Outputting the results of the 'test' method with different integer arrays and lengths as arguments
            Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7 }, 2)); // Testing the method with an array and a length
            Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7 }, 3)); // Testing the method with an array and a length
            Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7, 5 }, 3)); // Testing the method with an array and a length
        }       

        // Method to check if the first 'len' elements in the array are the same as the last 'len' elements
        static bool test(int[] numbers, int len)
        {
            int arra_size = numbers.Length; // Storing the length of the array

            for (int i = 0; i < len; i++) // Looping through the first 'len' elements
            {
                // Checking if the current element from the beginning and end of the array are different
                if (numbers[i] != numbers[arra_size - len + i])
                {
                    return false; // Returning false if any pair of elements are not equal
                }
            }

            return true; // Returning true if all 'len' pairs of elements are equal
        }    
    } 
}

Sample Output:

True
False
True
