문제

Whenever somebody goes to an ATM to withdraw or deposit money, a calculation has to be done to keep the person's bank balance correct. Your task in this problem is to do such calculations. There is a bank rule that says that a customer may not have an overdraft of more than $200, so any withdrawal that would take the balance below –200 must be stopped. (A minus sign is used to indicate an overdraft, or negative balance).

Each transaction consists of an integer representing the starting balance (between –200 and +10,000), the letter W or the letter D (Withdrawal or Deposit), followed by a second integer representing the amount to be withdrawn or deposited (between 5 and 400). Input will be terminated by a line containing 0 W 0.

출력
