The following array of windows pictured below consists of 6 rows of 5 windows each. Every window corresponds to one hotel room, and every hotel room has one light switch. The lights inside the hotel rooms have a strange property: whenever one switch is flipped, the lights in all rooms in the whole row switch on or off. (So in any of the 6 rows, all of the lights in that row are either on or off, and toggling any switch in that row will toggle the whole row) In this circuit, there are A SPDT and B DPDT switches. Find A x B.
