1️⃣ Setting the Scene

You have been asked to create a program to move rovers around the surface of Mars! ✨ The surface of Mars is represented by a Plateau. You can make the assumption that the 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 🌏

2️⃣ Your Task

👉 Choose an approach that you feel comfortable with to receive input into your program:

1. feeding input values into unit tests 👍
2. input via a console application; 🔥
3. supplying input via a file; 🔥 👉 Note that options 2 & 3 are a little trickier, as you have to account for external user input, which could be anything! 👀 There are some important notes on handling potential user input below! 👉 Create a program which implements the rules for the Mars Rover, which can be found at the end of this brief. ⚠️ IMPORTANT: Imagine that this isn’t simply a little kata, but instead the starting point of a whole app! Structure your code and files in such a way that it can scale as more features are added in future. We will assess how well you achieve this! 👉 Apply Test-Driven Development (TDD) to test-drive your solution as you build it. 👉 Create production-quality code. This means you have thought carefully about your code design and that your code is clean and well-tested.

⌨️ Inputs into the Program

First Line of Input to the Program

The first line inputted into the program represents the upper-right coordinates of the Plateau.

5 5

This Plateau has maximum (x, y) co-ordinates of (5, 5).

N.B. Assume that the lower-left coordinate is (0, 0).

Subsequent Lines of Input into the Program - Input to Rovers. This represents the instructions to move the rovers.

Each rover receives two lines of input.

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.

📏 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).

🗺️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

N.B. Assume that the square directly North from (x, y) is (x, y+1).
