# The Mars Rover Kata

Research suggests that the original version of this problem was part
of the Thoughtworks interview loop as far back as 2007. I haven’t
been able to find an authoritative source, but the consensus view
seems to be that the form was something like what follows below.

## Problem

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 their on-board cameras can get a complete view of the
surrounding terrain to send back to Earth.

A rover’s position and location is represented by a combination of x
and y co-ordinates and a letter representing 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).

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.

### EXAMPLE:

```
5 5
1 2 N
LMLMLMLMM
3 3 E
MMRMMRMRRM
```

##### Expected Output:
