# Mars Rover Challenge
## Setting the Scene
This is program to move rovers around the surface of Mars!
✨
The surface of Mars is represented by a Plateau,
Plateau is a square/rectangular grid for the purpose of this task.
Rovers navigate the Plateau so they can use their special cameras 📷 and robot arms
🦾 to collect samples back to Planet Earth 🌏
Representation of a Rover’s Position on the Plateau
The Plateau is divided into a grid. A Rover’s position is represented by x and y
co-ordinates and the letters N, S, W, E to represent North, South, West, East (the four
cardinal compass points) respectively.
Example
`0 0 N`
This means the Rover is at the bottom-left corner facing in the North direction.
N.B.
Assume that the square directly North from (x, y) is (x, y+1), and the square directly
East from (x, y) is (x + 1, y)
## Instructing a Rover to Move Around the Plateau
💻 To move a Rover around the Plateau, a string of letters is sent to a Rover.
Here are the letters and their resultant action:
**L**- Spins the Rover 90 degrees Left without moving from the current coordinate point
**R** - Spins the Rover 90 degrees Right without moving from the current coordinate point
**M** - Moves the Rover forward by one grid point, maintaining the same heading/orientation
Assume that the square directly North from (x, y) is (x, y+1).
## Inputs into the Program
### First Line of Input to a Rover
The Rover’s position is represented by two integers representing the X and Y coordinates and a letter representing where the Rover is facing (its orientation).
`1 2 N`
### Second Line of Input to a Rover
A string of letters representing the instructions to move the Rover around the Plateau.
`LMLMLMLMM`
### Movement Rules
Rovers move sequentially, this means that the first Rover needs to finish moving first
before the next one can move.
### Output
For each Rover, the output represents its final position (final coordinates and where it is facing).
### Lines of Input to the Program:
`5 5 // Plateau`
`LMLMLMLMM // Instructions`
`1 2 N // Rover Position`
`MMRMMRMRRM`
`3 3 E`
Expected Output:
`1 3 N // Rover Position`
`5 1 E // Rover Position`
