      Scanner sc =  new Scanner(System.in);
        String into = sc.next();
        int L = into.length();
        int L8 = (L%8 == 0) ? L : (L/8 + 1)*8;
        int add = L8 - L;
        int key = 0;
         for(int i = 0 ; i<L8 ;i++){
             if(i < L && key < L8 / 8){
                  System.out.print(into.charAt(i));
                  if((i+1)%8 == 0 ){
                       System.out.println("");
