Question: The lights in a classroom are controlled by two switches: one at the back and one at the front of the room. Moving either switch

The lights in a classroom are controlled by two switches: one at the back and one at the front of the room.

Let P and Q be input to switches and R be the output (light on/off), design a circuit to control the witches and give its corresponding truth table.
