+### Specification
+
+A squad of robotic rovers are to be landed by NASA on a plateau on Mars. This plateau, which is curiously rectangular, must be navigated by the rovers so that the on board cameras 
+can get a complete view of the surrounding terrain to send back to Earth. A rover’s position is represented by a combination of x and y co-ordinates and a letter presenting one of the 
+four cardinal compass points. The plateau is divided up into a grid to simplify navigation. An example position might be 0, 0, N, which means the rover is in the bottom left corner and 
+facing North.
+In order to control a rover, NASA sends a simple string of letters. The possible letters are ‘L’, ‘R’ and ‘M’. ‘L’ and ‘R’ makes the rover spin 90 degrees left or right respectively, without 
+moving from its current spot. ‘M’ means move forward one grid point, and maintain the same heading.
+Assume that the square directly North from (x, y) is (x, y+1).
+
+### Input
+The first line of input is the upper-right coordinates of the plateau, the lower-left coordinates are assumed to be 0,0. The rest of the input is information pertaining to the rovers that 
+have been deployed. Each rover has two lines of input. The first line gives the rover’s position, and the second line is a series of instructions telling the rover how to explore the 
+plateau. The position is made up of two integers and a letter separated by spaces, corresponding to the x and y co-ordinates and the rover’s orientation. Each rover will be finished 
+sequentially, which means that the second rover won’t start to move until the first one has finished moving.
+
+### Output
+The output for each rover should be its final co-ordinates and heading.
+
