Solution in C# (judge verdict: Wrong Answer)

using System;

namespace Test
{
	class Program
	{
		static void Main(string[] args)
		{
			int top1 = 0;
			int top2 = 0;
			int top3 = 0;
			for (int i = 0; i < 10; i++)
			{
				int n = int.Parse(Console.ReadLine());
				if (n > top1)
				{
					top1 = n;
				}
				else if (n > top2)
				{
					top2 = n;
				}
				else if (n > top3)
				{
					top3 = n;
				}
			}
			for (int i = 0; i < 3; i++)
			{
				if (top2 < top1 && top2 < top3)
				{
					Console.WriteLine(top3);
					top3 = -1;
				}
				else if (top2 < top1)
				{
					Console.WriteLine(top2);
					top2 = -1;
				}
				else
				{
					Console.WriteLine(top1);
					top1 = -1;
				}
