Sample Solution:

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(test("frizz"));
            Console.WriteLine(test("zane"));
            Console.WriteLine(test("Zazz"));
            Console.WriteLine(test("false"));
            Console.WriteLine(test("zzzz"));
            Console.WriteLine(test("ZZZZ"));
            Console.ReadLine();
        }
   public static bool test(string str)
        {
            int ctr = 0;
            for (int i = 0; i < str.Length; i++)
            {
                if (str[i] == 'z')
                {
                    ctr++;
                }
            }
            return ctr > 1 && ctr <= 4;
        }
    }
}

Sample Output:

True
False
True
False
True
False
