            Dictionary<string, int> memo = new Dictionary<string, int>();

            int maxV = 0;

            string[] txt = Console.ReadLine().Split(' ');

            foreach (var t in txt)
            {
                if (!memo.ContainsKey(t)) memo.Add(t, 1);
                else memo[t]++;

                if (maxV < memo[t])
