Interview Prompt

Implement bank_account_simulator(initial_balance, ops) that applies a list of ops to a BankAccount starting at initial_balance. Each op is one of ['deposit', amt], ['withdraw', amt], or ['balance']. A deposit adds amt to the balance; a withdraw subtracts amt but raises ValueError if amt is greater than the current balance; 'balance' is a read with no side effect. Return the final balance (an int) after applying every op. If any withdraw would overdraw the account, stop and return the string 'ValueError' instead. You must implement a BankAccount class (constructor, deposit, withdraw, and a balance property that raises on overdraft) and drive it from bank_account_simulator.

Summary

Deposits, withdrawals, and the risk of going negative.
