The board will eventually have more than two cell states as the program becomes more complicated, and it would be nice to add formatting to the printed output of the board to ensure readability as the number of board states increases.

To accommodate more board states and facilitate print formatting, we have provided the State enum with enumerator values kEmpty and kObstacle . In this exercise, you will write a CellString function which converts each State to an appropriate string. In the next exercise, we will update the program to use the enum values and CellString function.

To Complete This Exercise:

  1. Write a function CellString which accepts a State as input and returns the following string:
    • "⛰️ " if the input equals a kObstacle
    • "0 " otherwise.
