C# Sharp: Basic Algorithm Exercises - Check if a given array of integers contains no 3 or a 5

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[] { 3, 3, 3, 3 })); 
         Console.WriteLine(test(new[] { 3, 3, 3, 5, 5, 5})); 
         Console.WriteLine(test(new[] { 1, 6, 8, 10})); 
        }           
       static bool test(int[] nums)
         {
            var three = false;
            var five = false;

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

Sample Output:

True
True
False
True
