problem_description: Statement
  
  Iroha is very particular about numbers. There are K digits that she dislikes:
  D_1, D_2, ..., D_K.
  
  She is shopping, and now paying at the cashier. Her total is N yen (the
  currency of Japan), thus she has to hand at least N yen to the cashier (and
  possibly receive the change).
  
  However, as mentioned before, she is very particular about numbers. When she
  hands money to the cashier, the decimal notation of the amount must not
  contain any digits that she dislikes. Under this condition, she will hand the
  minimum amount of money.
  
  Find the amount of money that she will hand to the cashier.
