import java.util.Scanner;
public class SquareCharacterTriangle
{
 public static void main(String[] args) {
  char ch;
  Scanner sc = new Scanner(System.in);
  System.out.print("Enter last character of triangle : ");
  ch = sc.next().charAt(0);
  if (ch >= 'a' && ch <= 'z') {
   ch = (char)(ch - 32);
  }
  System.out.println();
  for (char r = 'A'; r <= ch; r++) {
   for (char c = r; c >= 'A'; c--) {
    System.out.print(c);
   }
   System.out.println();
  }
  for (char r = 'A';
   'A' <= ch; ch--, r++) {
   for (char c = (char)(ch - 1); c >= 'A'; c--) {
    System.out.print(c);
   }
   System.out.println();
  }
