If you ever wonder why you look for a job and see a bunch of agencies seeming to post the same contract, it's because The Map uses this projection capability to detect possible collisions and throw errors if necessary. Please install node > 12 with npm. // 3. This way, if the input or output ever needs to change, we can just change the interfaces instead of picking through the code for magic strings. A rovers position and location is represented by a combination of x and y co-ordinates and a letter representing one of the four cardinal compass points. The first line gives the rover's position, and the second line is a series Each rover will be finished sequentially, which means that the second rover wont start to move until the first one has finished moving.
