Refer to the example in the chapter regarding advertising expense accounts required for a department store. Assume that the store's accounting software permits a general ledger account number with the following attributes:

The first field consisting of three digits uniquely identifies the account, distinguishing it from other general ledger accounts and places it in the correct location in the chart of accounts.

The second field has four digits, each of which may be used as individual fields or used in combination.

The report writer for the software package permits you to use the question mark $(?)$ as a wildcard symbol when specifying which accounts to include in a report. For example, the specification $330.?4??$ includes in a report all accounts having the first field equal to $330$ and the second digit in the second field equal to $4.$
