What is the key characteristic of the algorithm represented in the alarm clock example that relates to control flow?
It uses a FOR loop.
It includes an IF statement to check the time.
It waits for a certain time to elapse and triggers a sound.
It implements a WHILE loop to check continuously.
Shpjegimi
The WHILE loop is used to repeatedly check the time until the alarm time is reached.
