06. Building (solutions with or not ternary operator)

using System;

namespace Building
{
    class Program
    {
        static void Main(string[] args)
        {
            int floors = int.Parse(Console.ReadLine());
            int volume = int.Parse(Console.ReadLine());

            for (int floor = floors; floor > 0; floor--)
            {
                char index = ' ';
                string currentFloor = "";
                for (int flat = 0; flat < volume; flat++)
                {
                    if (floors == floor)
                    {
                        index = 'L';
                    }
                    else
                    {
                        if (floor % 2 == 0)
                        {
                            index = 'O';
                        }
                        else
                        {
                            index = 'A';
                        }
                    }
                    currentFloor += $"{ index}{ floor}{ flat} ";
                }
                Console.WriteLine(currentFloor);
            }
        }
    }
}


Решение с тернарен оператор:

using System;

namespace Building
{
    class Program
    {
        static void Main(string[] args)
        {
            int floors = int.Parse(Console.ReadLine());
            int volume = int.Parse(Console.ReadLine());

            for (int floor = floors; floor > 0; floor--)
            {
                for (int flat = 0; flat < volume; flat++)
                {
                    Console.Write($"{ (floors == floor ? 'L' : floor % 2 == 0 ? 'O' : 'A')}{ floor}{ flat} ");
                }
                Console.WriteLine();
            }
        }
    }
}
