Solution in C# (judge verdict: Accepted)

using System;
 
public class test{
  static void Main (string[] args)
  {
    var first = 0;
    var second = 0;
    var therd = 0;
    var height = 0;
    for(int i = 0; i < 10; i++)
    {
        height = int.Parse(Console.ReadLine());
        if(height >= first)
        {
            therd = second;
            second = first;
            first = height;
        }
        else if(height >= second)
        {
            therd = second;
            second = height;
        }
        else if(height >= therd)
        {
            therd = height;
        }
    }
    
        Console.Write("{0}\n",first);
        Console.Write("{0}\n",second);
        Console.Write("{0}\n",therd);
