C# Sharp: Basic Algorithm Exercises - Check if an array of integers contains a 3 next to a 3 or a 5 next to a 5 or both

Sample Solution:

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {               
         Console.WriteLine(test(new[] { 5, 5, 5, 5, 5 })); 
         Console.WriteLine(test(new[] { 1, 2, 3, 4 })); 
         Console.WriteLine(test(new[] { 3, 3, 5, 5, 5, 5})); 
         Console.WriteLine(test(new[] { 1, 5, 5, 7, 8, 10})); 
        }           
       static bool test(int[] numbers)
         {
            for (int i = 0; i < numbers.Length - 1; i++) if ((numbers[i] == 3 && numbers[i + 1] == 3) || (numbers[i] == 5 && numbers[i] == 5)) return true;
	return false;
         }    
   } 
}

Sample Output:

True
False
True
True
