Coordinates can not be of negative value" means that the x and y coordinates of the rovers' positions on the mentioned surface cannot have negative values. In other words, the rovers cannot be positioned at locations with negative x or y values. This assumption helps define the boundaries of the area in which the rovers can move and explore on Mars.

indicates that the maximum values for the x and y coordinates of the grid (or plateau) on which the Mars rovers operate cannot be negative. This ensures that the grid's boundary is defined in a way that avoids negative coordinates and establishes a non-negative coordinate space for the rovers to navigate within. It's a constraint that helps maintain the validity of the grid's dimensions and prevents rovers from going beyond its specified boundaries.

• Make you ruby is installed locally. Visit this guide for installation steps using rbenv

• clone this repository to your local machine

• navigate to the repository follow terminal

• run the following command to start the commandline program

  bin/mars_rovers {x} {y}

  Place {x} and {y} with the sizr fo the grid (plateau) Keep in mind that (x,y) should be positive integers

  if {x} {y} are not passed, the max grid defaults to (5,5)

• the command above result it permissions related issue, try running commnd to grant the script file permission, then run the script again.

    chmod +x bin/mars_rovers

• You can also run the script directly with ruby

   ruby bin/mars_rovers 

• I have also published a ruby gem you can install and test it from there

    gem install mars_rovers_dellan

    ruby mars_rovers 5 5

• You will be prompted to enter an intial position of a rover x y N

• For example 1 2 N

• Next you will be prompted to enter the motion command of the format LRM

  • L - turn left
  • R - turn right
  • M - move

• Example command is LMLMLMLMM

• The new location will be printed.

• You can keep adding ass many rovers as you'd like

• Use the print command to output the locations for all the rovers added
