Program Description Answer

When a method is called from the main method then, it calls itself four times and the depth of the recursion will be four.

Hence, the correct option is “B”.

Expert Solution & Answer
Check Mark

Explanation of Solution

Four:

The depth of the recursion depends on the number of times the method calls itself.

Explanation for incorrect options:

One:

The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.

Hence, option “A” is wrong.

Five:

The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.

Hence, the option “C” is wrong.

Nine:

The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.

Hence, the option “D” is wrong.

Change the following code so that there is always at least one way to get from the left corner to the top right, but the labyrinth is still randomized. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. Take care that the player and the dragon cannot start off on walls. Also the dragon starts off from a randomly chosen position   public class Labyrinth {    private final int size;    private final Cell[][] grid;     public Labyrinth(int size) {        this.size = size;        this.grid = new Cell[size][size];        generateLabyrinth();    }     private void generateLabyrinth() {        Random rand = new Random();        for (int i = 0; i < size; i++) {            for (int j = 0; j < size; j++) {                // Randomly create walls and paths                grid[i][j] = new Cell(rand.nextBoolean());            }        }        // Ensure start and end are…
