Solution in C# (judge verdict: Wrong Answer)

public class Hello{
    public static void Main(){
        int f = 0;
        int s = 0;
        int t = 0;
        for(int i=0;i<10;i++)
        {
            int height = int.Parse(System.Console.ReadLine());
            if(t > height)
            {
                t = height;
            }
            if(s > height)
            {
                t = s;
                s = height;
            }
            if(f > height)
            {
                s = f;
                f = height;
            }
        }
        System.Console.WriteLine(f.ToString());
        System.Console.WriteLine(s.ToString());
        System.Console.WriteLine(t.ToString());
    }
