Consider a single platter disk with the following parameters:
rotation speed: 7200 rpm
number of tracks on one side of platter : 30,000
number of sectors per track: 600
seek time: 1 ms for every hundred tracks traversed.
let the disk receive a request to access a random sector on arandom track and assume the head starts at track 0.
a)what is the average seek time?
b)what is average rotational latency?
c)what is the transfer rate for a sector?
d)what is the total average time to satisfy a request?

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.
