Task «Class for managing a bank account with transaction history»
Create a class `BankAccount` that stores a balance and a list of transactions. Implement the following methods: `deposit(double amount)` — deposit, `withdraw(double amount)` — withdrawal (cannot go negative), `getBalance()` — current balance, `getTransactionHistory()` — returns a list of strings in the format `"Deposit: 100.0"` or `"Withdraw: 50.0"`. In `main`, read from `stdin` the number of operations `n`, then `n` lines: each line contains `"D amount"` (deposit) or `"W amount"` (withdrawal). After processing all operations, output the final balance and the transaction history (each on a new line). Constraints: the amount is a positive `double`, `n ≤ 100`.
Input Format
The first line contains an integer n — the number of operations. Then n lines: each contains a character 'D' or 'W' and a space-separated floating-point number — the amount of the operation.
Output Format
First line: "Balance: X.XX" (balance with two decimal places). Then for each operation, a line of the form "Deposit: X.XX" or "Withdraw: X.XX" in the order of execution.
