Solution in C# (judge verdict: Accepted)

using System;

namespace AOJ_Progran
{
    class Program
    {
        static void Main(string[] args)
        {
            int first, second, third;
            int[] mountains = new int[10];
            for(int i =0;i<10;i++)
            {
                mountains[i] = int.Parse(Console.ReadLine());
            }
            Array.Sort(mountains);
            first = mountains[9];
            second = mountains[8];
            third = mountains[7];

            Console.WriteLine(first);
            Console.WriteLine(second);
            Console.WriteLine(third);
