e need to design an dimplement a class that will be used to represent bank accounts.

We want the following functionality and characteristics:

• accounts are uniquely identified by an account number (assume it will just be passed in the initializer)
• account holders have a first and last name
• accounts have an associated preferred time zone offset (e.g. -7 for MST)
• balances need to be zero or higher, and should not be directly settable.
• but, deposits and withdrawals can be made (given sufficient funds)
  • if a withdrawal is attempted that would result in nagative funds, the transaction should be declined.
• a monthly interest rate exists and is applicable to all accounts uniformly. There should be a method that can be called to calculate the interest on the current balance using the current interest rate, and add it to the balance.
• each deposit and withdrawal must generate a confirmation number composed of:
  • the transaction type: D for deposit, and W for withdrawal, I for interest deposit, and X for declined (in which case the balance remains unaffected)
  • the account number
  • the time the transaction was made, using UTC
  • an incrementing number (that increments across all accounts and transactions)
  • for (extreme!) simplicity assume that the transaction id starts at zero (or whatever number you choose) whenever the program starts
  • the confirmation number should be returned from any of the transaction methods (deposit, withdraw, etc)
• create a method that, given a confirmation number, returns:
  • the account number, transaction code (D, W, etc), datetime (UTC format), date time (in whatever timezone is specified in te argument, but more human readable), the transaction ID
  • make it so it is a nicely structured object (so can use dotted notation to access these three attributes)
  • I purposefully made it so the desired timezone is passed as an argument. Can you figure out why? (hint: does this method require any information from any instance?)
