Mars Rover using DDD

About

The Purpose of this repo is

Develop an API that moves a rover around on a grid. You are given the initial starting point (x,y) of a rover and the direction (N,S,E,W) it is facing.

  • The rover receives a character array of commands.
  • Implement commands that move the rover forward/backward (f,b).
  • Implement commands that turn the rover left/right (l,r).
  • Implement wrapping from one edge of the grid to another. (planets are spheres after all)
  • Implement obstacle detection before each move to a new square.
  • Implement functionality to undo the command(s). If a given sequence of commands encounters an obstacle, the rover moves up to the last possible point and reports the obstacle.
