Question 1

For the questions below, consider the following representation of grid and the maze code from Chapter 11.



Assume valid returns true if row and column are >= 0 and <= the grid's row length or column length and the entry at this position = = 1.  And assume TRIED = 3 and PATH = 7
  

Which of the following grids would be the result after traverse has completed all of its recursive calls?
◦ 1 1 1 1 1 1 0 0
0 0 1 0 0 1 0 0
0 0 1 0 0 1 1 0
