So far, you have many used expectations to check for equality. the rover's properties. of each class is below. Think, what the if-based code would look like if NASA says: "Oh, we want rover to support A direction for turning 45 degrees left, and B for 45 degrees right, and R to fully reverse -- 180 degrees!". 'M' means move Code a third test using, "constructor sets a value passed in as the 2nd Why is this the case? Each rover will be finished sequentially, which means that the second rover This has a fundamental difference (basically, it's following the idea of "Strategy" design pattern). Before you start coding the game itself, you'll need to build the environment where the game will take place and begin to create rules for how that environment will operate. description. LMLMLMLMM It may help to put the rover and the hazards, along with their rules for moving, in one loop, but this can be done across multiple loops or even across multiple libraries. // Output: The rover's current coordinates are (0, 2) and it is facing N of instructions telling the rover how to explore the plateau.
