# Mars Rover

## The Task

Firstly, determine a map grid with width and height.

Then place a "Mars Rover" at a given position and facing direction on that grid. Then give it a set of directions:

 - F = Forward

 - L = Left

 - R = Right

 

Finally report the Rover's final location along with the way it is facing. If it is off-grid, report it's last known location.

This task was described in plain text and I was told to use any language and framework. I chose Laravel.

## Setup

```

git clone [email protected]:davidpeach/Rover.git

# or

git clone https://github.com/davidpeach/Rover.git

cd ./Rover

composer install

```

## Running the Test Suite

```

./vendor/bin/phpunit

```

## Running

Below is an example of the questions it will ask you along with example responses you could give.

```

php artisan rover:setup

What is the map size?:

 > # 4 8 (Map grid 4 blocks wide by 8 blocks high - zero indexed)

Please give a mapping.:

> # (2, 3, N) FLLFR

Do you wish to add another mapping? (yes/no) [no]:

> # yes

Please give a mapping.:

> # (1, 0, S) FFRLF

Do you wish to add another mapping? (yes/no) [no]:

> # yes

Please give a mapping.:

> # (2, 2, N) RFLFFFFFF

Do you wish to add another mapping? (yes/no) [no]:

> # no

## You should then receive a response like this:

(2, 3, W)

(1, 0, S) LOST

(3, 7, N) LOST

```
