            int[] arr = { -32, 53, 5, -34, 56, 45, 34, 5, -34, 45, 2, 3, 6 };
            var query = arr.Distinct();
            foreach (var item in query)
            {
                Console.Write(item + "  ");
            }
            string[] strArr = { "hi", "Hello", "hack", "sit", "stack", "sad", "suit", "shit", "wade", "world" };

            MyStrEqulComparer mystr = new MyStrEqulComparer();
            var query2 = strArr.Distinct(mystr);
            Console.WriteLine();
            foreach (var item in query2)
            {
                Console.Write(item + "    ");
            }
