Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace

namespace CheckArray // Defining a namespace called 'CheckArray'
{
    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 as arguments
            Console.WriteLine(test(new[] { 3, 5, 1, 5, 3, 5, 7, 5, 1, 5 })); // Testing the method with various arrays
            Console.WriteLine(test(new[] { 3, 5, 5, 5, 5, 5, 5 })); // Testing the method with various arrays
            Console.WriteLine(test(new[] { 3, 5, 2, 5, 4, 5, 7, 5, 8, 5 })); // Testing the method with various arrays
            Console.WriteLine(test(new[] { 2, 4, 5, 5, 5, 5 })); // Testing the method with various arrays
            Console.WriteLine(test(new[] { 3, 5, 5, 5, 5, 5, 5, 5, 5, 5 })); // Testing the method with various arrays
        }

        // Method to check if the array contains exactly five occurrences of '5', with no adjacent '5's
        static bool test(int[] arr)
        {
            int ctr = 0; // Counter to track the occurrences of '5'

            for (int i = 0; i < arr.Length; i++) // Looping through the elements of the array
            {
                if (arr[i] == 5) // Checking if the element is '5'
                {
                    ctr++; // Incrementing the counter for each occurrence of '5'

                    // Checking if the next element is also '5' when '5' is found
                    if (i < arr.Length - 1 && arr[i + 1] == 5)
                    {
                        return false; // Returning false if consecutive '5's are found
                    }
                }
            }

            // Returning true if exactly five occurrences of '5' are found with no consecutive '5's
            return ctr == 5;
        }
    }
}

Sample Output:

True
False
True
False
False
