Part A:

• Create helper functions to make comparing things easier

  • Create an isValidPosition function to take 1 Location object and determine whether it's on the grid. Return true if it is, false otherwise. Use this function in getNextLoc to make your conditions shorter and more readable.

• Have a condition in getNextLoc that checks for both positions being invalid.  Return null if it is.

Part B:

• Try solving part B recursively...
