A Special Interest Group consortium (SIG) formed in 1998 to develop a wireless standard for interconnecting computing and communication devices and accessories, called Bluetooth. With Bluetooth:

A. all manner of consumer electronic devices, from mobile phones and laptops to headsets, printers, and keyboards, can be connected to each other
B. the intercom profile allows for voice communication between a headset and its base station
C. the radio layer establishes a logical link from slave to master (similar to a connection)
D. the Bluetooth protocol architecture has 17 layers

Duplicating objects creates copies that a. move differently than the original object b. erase the original object c. look and act like the original object d. add events to a game

You will be given two character arrays of the same size, one will contain a number of ships. ships will move around the character array based on which way they are facing and the route they are on. routes are given in the other array. the route consists of '-' and '|' for straight paths, '\' and '/' for curves, and '+' for intersections. there are ships on these routes. ships always face a direction, '^' for up, '> ' for right, 'v' for down, and '< ' for left. any time the ships hit a '\' or a '/' it will turn as you would expect a ship to turn (e.g. a '^' that moves into a '/' will turn right). at an intersection, ships will always continue straight through. all ships move at the same speed, ships take turns moving and all ships move during one 'tick'. the one in the most top left goes first, followed by those to its right, then the ones in the next row. it iterates along the rows and then down the columns. each ship moves one space on its turn moving along the route. your function needs to return the position of the first collision between two ships and the number of ticks before the crash occurred.
