| # | |
| # A robotics company named Trax has created a line of small self-driving robots | |
| # designed to autonomously traverse desert environments in search of undiscovered | |
| # water deposits. | |
| # | |
| # A Traxbot looks like a small tank. Each one is about half a meter long and drives | |
| # on two continuous metal tracks. In order to maneuver itself, a Traxbot can do one | |
| # of two things: it can drive in a straight line or it can turn. So to make a |

| # Modify the the search function so that it becomes | |

| # Your function should return the expanded grid | |
| # which shows, for each element, the count when | |
| # it was expanded or -1 if the element was never expanded. |
