Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;
namespace exercises
{
   class Program
    {
       static void Main(string[] args)
        {
            Console.WriteLine(test(new[] { 5, 5, 2 }));
            Console.WriteLine(test(new[] { 5, 5, 2, 5, 5 }));
            Console.WriteLine(test(new[] { 5, 6, 2, 9 }));
            Console.ReadLine();
        }
         public static int test(int[] numbers)
        {
            var ctr = 0;
            for (var i = 0; i < numbers.Length - 1; i++)
            {
                if (numbers[i].Equals(5) && (numbers[i + 1].Equals(5) || numbers[i + 1].Equals(6))) ctr++;
            }
            return ctr;
        }
    }
}

Previous: Write a C# Sharp program to create a new string of the characters at indexes 0,1, 4,5, 8,9 ... from a given string.
Next: Write a C# Sharp program to check if a triple is presents in an array of integers or not. If a value appears three times in a row in an array it is called a triple.
