Solution in C# (judge verdict: Accepted)

using System;
					
public class Program
{
	public static void Main()
	{
		int[] height, highest;
		
		height = new int[11];
		highest = new int[4]{0,0,0,0};
		
		for(int i = 1; i <= 10; i++)
		{
		height[i] = Int32.Parse(Console.ReadLine());
		
		  for(int j = 1; j<=3; j++)
		  {
		
		    if(height[i] > highest[j])
			{
			 highest[j-1]=highest[j];
			 highest[j]=height[i];
									
		    }
		
		  }
		
		}
		
		
		Console.WriteLine(Convert.ToString(highest[3]) + "\n" + Convert.ToString(highest[2]) +"\n"+ Convert.ToString(highest[1]));
	
}
}
