      System.out.print("enter values");
      int N,i,stringplace,check;
       char st;
      stringplace=-1;
       check=0;
       boolean t=false;
       N=sc.nextInt();
      String banner[]=new String[N];
       if(N>9)
         {
      System.out.println("invalid input");
         }
     for(i=0;i<N;i++)// arrray input
       {
      banner[i]=sc.next();//enter the teams names
       }
    while(!t)//!t(equals true so it will works)
      { 
      ++stringplace;
       for(i=0;i<N;i++)
          {  
      try{st=banner[i].charAt(stringplace);
       System.out.print(""+st+"       ");
        }
  catch(Exception          StringIndexOutOfBoundsException)
    {
           check++;
  System.out.print("        ");
    }
    }
  if(check>=N)
t=true;
          System.out.println();
  check=0;
}
