## Problem
|
||||
|
||||
MIT - feel free to use and modify.
|
||||
NASA is landing a robotic rover on a rectangular plateau on Mars.
|
||||
This plateau must be explored systematically so that the rover’s on-board cameras can survey the terrain and send images back to Earth.
|
||||
|
||||
A rover’s position is represented by:
|
||||
- Two integers (**X**, **Y**) indicating its coordinates, and
|
||||
- A letter indicating its current heading:
|
||||
- **N** (North)
|
||||
- **E** (East)
|
||||
- **S** (South)
|
||||
- **W** (West)
|
||||
|
||||
The plateau is divided into a grid, and the rover moves across it based on simple navigation commands.
|
||||
|
||||
For example, a position of `0 0 N` means the rover is at the bottom-left corner, facing North.
|
||||
|
||||
---
|
||||
|
||||
## Instructions
|
||||
|
||||
NASA can send the following commands to the rover:
|
||||
|
||||
- `L` ➔ Turn 90 degrees **left** without moving from the current spot.
|
||||
- `R` ➔ Turn 90 degrees **right** without moving from the current spot.
|
||||
- `M` ➔ Move **forward** one grid point in the direction it is facing.
|
||||
|
||||
> **Important**:
|
||||
> Moving North from `(x, y)` goes to `(x, y+1)`.
|
||||
> Moving East from `(x, y)` goes to `(x+1, y)`, and so on.
|
||||
|
||||
---
|
||||
|
||||
## Input
|
||||
|
||||
The input consists of:
|
||||
|
||||
1. **First parameter**: The rover’s **starting position**: two integers and a letter (e.g., `1 2 N`).
|
||||
|
||||
2. **Second parameter**: A string of **movement instructions** (e.g., `LMLMLMLMM`).
|
||||
|
||||
The rover processes all instructions in sequence.
|
||||
|
||||
---
|
||||
|
||||
## Output
|
||||
|
||||
After executing all the commands, the rover reports its **final coordinates and heading**.
|
||||
|
||||

|
||||
|
||||
## Example
|
||||
|
||||
| Starting Position | Instructions | Expected Output |
|
||||
|:------------------|:-------------|:----------------|
|
||||
| 1 2 N | | 1 2 N |
|
||||
| 1 2 N | L | 1 2 W |
|
||||
| 1 2 W | L | 1 2 S |
|
||||
| 1 2 S | L | 1 2 E |
|
||||
| 1 2 E | L | 1 2 N |
|
||||
| 1 2 N | R | 1 2 E |
|
||||
| 1 2 E | R | 1 2 S |
|
||||
| 1 2 S | R | 1 2 W |
|
||||
| 1 2 W | R | 1 2 N |
|
||||
| 1 2 N | M | 1 3 N |
|
||||
| 1 2 E | M | 2 2 E |
|
||||
| 1 2 S | M | 1 1 S |
|
||||
| 1 2 W | M | 0 2 W |
|
||||
| 1 2 N | LMLMLMLMM | 1 3 N |
|
||||
| 3 3 E | MMRMMRMRRM | 5 1 E |

# 🎯 Your Mission
|
||||
|
||||
You have been given a **working but fragile** codebase that controls a **single** rover.
|
||||
|
||||
Your goal:
|
||||
- **Refactor** the code to make it clean, expressive, and easy to maintain.
|
||||
- Prepare the code for **future enhancements**.
|
||||
- Eliminate technical debt, improve readability, and structure it to allow **easily adding new features** later.
|
||||
|
||||
> 🧠 **Hint**:
|
||||
> Future missions may require **handling multiple rovers** at once.
|
||||
> Your design should naturally evolve toward making this possible.
|
||||
|
||||
✅ **Do not change the existing behavior.**
|
||||
✅ **All existing tests must continue to pass.**
|
||||
