C# Sharp: Basic Algorithm Exercises - Check whether a given array of integers contains 5's and 7's

Sample Solution:

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {               
         Console.WriteLine(test(new[] { 1, 5, 6, 9, 10, 17 })); 
         Console.WriteLine(test(new[] { 1, 4, 7, 9, 10, 17 })); 
         Console.WriteLine(test(new[] { 1, 1, 2, 9, 10, 17})); 
        }           
       static bool test(int[] nums)
         {
             for (int i = 0; i < nums.Length; i++)
            {
                if (nums[i] == 5 || nums[i] == 7) return true;
            }

            return false;
          }
   } 
}

Sample Output:

True
True
False
