Now, create a destination that the rover will need to reach to succeed in its mission. forward one grid point, and maintain the same heading. // Input: L cause excessive frustration. You can also introduce levels into your game, adding hazards that are more challenging to overcome as the levels progress. // 1. 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. Dictionary for the rovers to reference depending on the direction they are facing: The main function that takes the input and gives the desired output: Functions that parse the input string and prints the output string. Work fast with our official CLI. //Create another function called moveBackward() that will move the rover back.
