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 result of the 'test' method with different integer arrays as arguments
            Console.WriteLine(test(new[] { 1, 5, 6, 9, 10, 17 })); // Testing the method with an array
            Console.WriteLine(test(new[] { 1, 5, 5, 9, 10, 17 })); // Testing the method with another array
            Console.WriteLine(test(new[] { 1, 5, 5, 9, 10, 17, 5, 5 })); // Testing the method with a third array
        }           

        // Method to check if there are adjacent occurrences of the number 5 in the array
        static bool test(int[] nums)
        {
            // Looping through the array except for the last element
            for (int i = 0; i < nums.Length - 1; i++)
            {
                // Checking if the current element is 5 and if the next element is also 5
                if (nums[i] == 5 && nums[i] == nums[i + 1])
                {
                    return true; // If two consecutive 5s are found, returning true
                }
            }

            return false; // If no consecutive 5s are found, returning false
        }
    } 
}

Sample Output:

False
True
True

Previous: Write a C# Sharp program to compute the sum of the numbers in a given array except those numbers starting with 5 followed by at least one 6. Return 0 if the given array has no integer.
Next: Write a C# Sharp program to check whether a given array of integers contains 5's and 7's.
