You are running through a dark cave, and suddenly you find yourself at a dead end. But, there is hope. You encounter a row of 5 lightbulbs that are turned off. Each have a switch that toggles whether they are on or off.
The wall in front of you will open up if all 5 lightbulbs are on at once.
Unfortunately, there is a catch.
When you toggle a lightbulb, the lightbulbs to the left and right will also toggle. If the lightbulb is at the end of the row, then toggling it will turn on just its one neighbor.
Another catch: Once you press 4 switches, the switches will deactivate and stop working.
How are you going to turn on all the lightbulbs to unlock the wall and get through?
Bonus: Can you solve the puzzle in exactly four toggles? Note, you must switch at least 3 unique switches. And, you may not toggle a single switch twice in row.
