Flipping the bulbs is an illustration of sequence and patterns
19 bulbs would remain on.
<h3>How to determine the number of bulbs that will be on</h3>
The sequence of turning the bulbs off and on, would change the state of the bulbs until the 380th process.
While changing the state of the bulbs, the bulb at the perfect square positions would remain on.
