Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
public class Hello{
    public static void Main(){
        int[] Top = new int[Consts.TOPNUM];
        int Elevation;
        for(int i = 0; i < Consts.MAX_MOUNTAINS; i++){
            Elevation = int.Parse(Console.ReadLine());
            for(int n = 0; n < Consts.TOPNUM; n++){
                if(Top[n] < Elevation){
                    for(int n2 = Consts.TOPNUM - 1; n2 > n; n2--){
                        Top[n2] = Top[n2 - 1];
                    }
                    Top[n] = Elevation;
                    break;
                }
            }
        }
        for(int i = 0; i < Consts.TOPNUM; i++)
            Console.WriteLine(Top[i]);
    }
}

public static class Consts{
    public static int MAX_MOUNTAINS = 10;
    public static int TOPNUM = 3;
