import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    int number = scanner.nextInt();
    int x = 1, n = 1;
    while (x <= number) {
      for (int i = 0; i < n; i = i + 1)
        if (x <= number)
          System.out.print(x++);
      System.out.println();
      n = n + 1;
    }
  }
