Entry and exit flow in LLD - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the entry point of the system flow.

LLD

def system_entry():
    print("System is starting...")
    [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using exit or shutdown functions in the entry flow.

The entry flow should initialize components to start the system properly.

2fill in blank

medium

Complete the code to define the exit point of the system flow.

LLD

def system_exit():
    print("System is shutting down...")
    [1]

Drag options to blanks, or click blank then click option'

Ainitialize_components()

Bstart_services()

Cshutdown_components()

Dlog_start()

💡 Hint

Common Mistakes

Calling initialization or start functions during exit.

The exit flow should properly shutdown components to close the system safely.

3fill in blank

hard

Fix the error in the flow control to ensure proper entry and exit.

LLD

def main_flow():
    [1]
    process_tasks()
    system_exit()

Drag options to blanks, or click blank then click option'

Asystem_exit()

Bsystem_entry()

Cprocess_tasks()

Dlog_error()

💡 Hint

Common Mistakes

Calling exit before entry or processing.

The main flow should start with system_entry to initialize before processing tasks.

4fill in blank

hard

Fill both blanks to correctly handle entry and exit logging.

LLD

def system_flow():
    [1]  # Log entry
    system_entry()
    process_tasks()
    system_exit()
    [2]  # Log exit

Drag options to blanks, or click blank then click option'

Alog_entry()

Blog_exit()

Clog_start()

Dlog_shutdown()

💡 Hint

Common Mistakes

Swapping entry and exit logs.

Using unrelated log functions.

Logging entry and exit helps track system flow start and stop events.

5fill in blank

hard

Fill all three blanks to implement a safe entry and exit flow with error handling.

LLD

def safe_system_flow():
    try:
        [1]  # Initialize
        process_tasks()
    except Exception as e:
        [2]  # Handle error
    finally:
        [3]  # Ensure exit

Drag options to blanks, or click blank then click option'

Asystem_entry()

Blog_error(e)

Csystem_exit()

Dprocess_tasks()

💡 Hint

Common Mistakes

Not calling exit in finally block.

Logging errors outside except block.

Entry initializes, errors are logged, and exit always runs to clean up.
