Task

📝 **Task:** Predict the final value of \`counter\` after 5 threads each run \`bump()\` once, with the lock protecting the increment.

📋 Edit the starter code below. Tests run automatically.

💡 **Hint:** Re-read the theory if you get stuck.

🔮 Predict the output

Read the code carefully

import threading

counter = 0
lock = threading.Lock()

def bump():
    global counter
    with lock:
        counter += 1

threads = [threading.Thread(target=bump) for _ in range(5)]
for t in threads: t.start()
for t in threads: t.join()
print(counter)
