My Notes

I chose node js and tried to make it in the simplest way possible for readablity and maintainability.

index.js is the entry pointto get the parameters (input)
/src/move.js is the logic
/src/move.test.js is the unit tests

Installation and Starting up

Pull the repository and run npm i to install packages
Type npm start to run the application
Type npm test to run unit tests

Test Description

You need to develop a robot that will navigate on Mars terrain.

The input of the app will be a series of commands to move the robot on the plateau. Mars plateau is a grid defined by the initial input of the app, such as 5x5, 3x4, etc.

The second input line will be a string containing multiple commands as described below:

L: Turn the robot left
R: Turn the robot right
F: Move forward on it's facing direction

Sample command string: LFLRFLFF

The robot will always start at X: 1, Y: 1 facing NORTH.

If the robot reaches the limits of the plateau the command must be ignored.

Your goal is to navigate the robot and print the final position.

Example:

Input:

5x5

FFRFLFLF

Result:

1,4,West

There is no limit for the Plateau size
Inputs will always be valid, so there is no need to validate them
There is no 0,0 position
