Bank Account Operations Simulation

In this problem, you are to simulate operations on bank accounts. There are three types of accounts:

• Account: Supports deposit and withdrawal operations. Withdrawals are only processed if sufficient funds are available.
• CheckingAccount: Inherits from Account and permits overdraft withdrawals up to a specified overdraft limit.
• SavingsAccount: Inherits from Account and supports the application of interest. Interest is applied only when the balance is positive. The new balance is computed using the formula: \( new\;balance = old\;balance + old\;balance \times interest\_rate \).

Your program will process a series of commands provided via standard input and output the balance for every check_balance command.

inputFormat

The input begins with an integer ( Q ) representing the number of operations. Each of the following ( Q ) lines contains one command. The available commands are:

• create [AccountType] [parameters]: Initializes an account. For an Account, provide the initial balance. For a CheckingAccount, provide the initial balance and overdraft limit. For a SavingsAccount, provide the initial balance and interest rate.
• deposit x: Deposits the integer \( x \) into the account (only if \( x > 0 \)).
• withdraw x: Withdraws the integer \( x \) from the account if the conditions for withdrawal are met.
• apply_interest: For SavingsAccount only, applies interest as per the formula above (does nothing for other account types).
• check_balance: Prints the current balance to standard output.

For each check_balance command, print the current balance on a new line to standard output.## sample
