import java.util.Scanner;

public class q12606 {
public static void
main(String args[]) {
Scanner in = new Scanner(System.in);
String
input = in.nextLine();
String [] splitted = input.toLowerCase().split("
");
int maxLength = 0;
for (int i = 0; i < splitted.length;
i++)
if (splitted[i].length() > maxLength)
maxLength =
splitted[i].length();
String output = "";
for (int i = 1; i <=
maxLength; i++)
for (int j = 0; j < splitted.length; j++)

if (splitted[j].length() == i)
output += splitted[j] + " ";

output = Character.toUpperCase(output.charAt(0)) + output.substring(1);

System.out.println(output);
}
}
