 char s[2];
 int c,y,x,ya,xa,minyaxa;
 while (1) {
  scanf("%1s",s);
  c=s[0];
  if (c=='#') break;
  c=c-'A';
  for (y=-c;y<=c;y++) {
   for (x=-c;x<=c;x++) {
    xa=x; if (xa<0) xa=-xa;
    ya=y; if (ya<0) ya=-ya;
    minyaxa=xa; if (minyaxa>ya) minyaxa=ya;
    printf("%c",c-minyaxa+'A');
   }
   printf("\n");
  }
 }
 return 0;
