Решение с масив:

using System;

namespace Messages
{
    class Program
    {
        static void Main(string[] args)
        {
            int num = int.Parse(Console.ReadLine());
            int[] button = { 32, 0, 97, 100, 103, 106, 109, 112, 116, 119 };
            string message = "";

            for (int i = 0; i < num; i++)
            {
                int current = int.Parse(Console.ReadLine());
                message += (char)(button[current % 10] + current.ToString().Length - 1);
            }
            Console.WriteLine(message);
        }
    }
}
