Sample Solution:

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {               
         Console.WriteLine(test(new[] { 3, 5, 1, 3, 7 })); 
         Console.WriteLine(test(new[] { 1, 2, 3, 4 })); 
         Console.WriteLine(test(new[] { 3, 3, 5, 5, 5, 5})); 
         Console.WriteLine(test(new[] { 2, 5, 5, 7, 8, 10})); 
        }           
       static bool test(int[] numbers)
         {
          bool three = false;

            for (int i = 0; i < numbers.Length; i++)
            {
                if (three && numbers[i] == 5) return true;
                if (numbers[i] == 3) three = true;
            }
            return false;
         }    
   } 
}

Sample Output:

True
False
True
False
