Weird Wally's Wireless Widgets, Inc. manufactures an eclectic assortment of small, wireless, network capable devices, ranging from dog collars, to pencils, to fishing bobbers.

In order to provide some security for transmissions to and from the devices, WWWW uses the following algorithm, which you are to implement. Weird Wally's Wirele
