Banking System with Transaction Activity

Design and implement a banking system that supports account creation, deposit, withdrawal, and transfer operations. The system should log transaction activities for each account and allow querying of the top N active accounts. Ensure good object-oriented design and error handling. The system might extend to concurrency control and data consistency. Example Input create account=1 deposit account=1 amount=100 withdraw account=1 amount=50 transfer from=1 to=2 amount=25 query top_n=1
