import java.util.Scanner;

public class Main {

        Scanner input = new Scanner(System.in);

        int [] a = new int [5];
        for (int i = 0; i < 5; i ++){
            a[i] = input.nextInt();
        }

        for (int i = 0; i < 5; i ++) {
            for (int j = i + 1; j < 5; j ++){
                if (a[i] > a[j]) {
                    int t = a[i];
                    a[i] = a[j];
                    a[j] = t;
                }
            }
        }

        for (int i = 0; i < 5; i ++){
