In a bank, there are many accounts. An account can be a normal account or a VIP account.

Account information is stored in a file in the following format (account.txt):

Every account number (accountNo) contains four digits. Password would be a 6-sigits number. For

every account, the client can inquiry, withdraw, save and transfer money. These transactions have

the following features:

1. Withdraw

For normal account, the customer can withdraw at most 2000 per time. For VIP account,

the customer can withdraw 3000 per time. If a customer wants to get money that

exceeds this limit, a warning should be given.

When a customer withdraws money from an account and the amount exceeds the

budget in that account, the withdrawal fails. A warning must be given.

account can transfer at most 10000. It is assumed that the accounts transferring from

the transaction is 0.5%; otherwise, the charge is 1%.
