For the Questions Below, Consider the Following Representation of Grid

question 4

Multiple Choice

For the questions below, consider the following representation of grid and the maze code from Chapter 11.
Grid:
1 1 1 1 1 1 0 0
0 0 1 0 0 1 0 0
0 0 1 0 0 1 1 0
0 0 1 1 0 0 1 0
0 0 0 1 1 0 0 0
0 0 0 0 1 1 1 1
Code:
public boolean traverse(int row, int column)
{
if (valid(row, column) )
{
boolean done = false;
grid[row][column] = TRIED;
if (row == grid.length - 1 && column == grid[0].length - 1)
done = True;
else
{
done = traverse(row + 1, column) ;
if (!done) done = traverse(row, column + 1) ;
if (!done) done = traverse(row - 1, column) ;
if (!done) done = traverse(row, column - 1) ;
}
if (done) grid[row][column] = PATH;
}
return done;
}
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?

• A) 1 1 1 1 1 1 0 0 0 0 1 0 0 1 0 0
• 0 0 1 0 0 1 1 0
• 0 0 1 1 0 0 1 0
• 0 0 0 1 1 0 0 0
• 0 0 0 0 1 1 1 1
• B) 3 3 3 3 3 3 0 0 0 0 3 0 0 3 0 0
• 0 0 3 0 0 3 3 0
• 0 0 3 3 0 0 3 0
• 0 0 0 3 3 0 0 0
• 0 0 0 0 3 3 3 3
• C) 7 7 7 3 3 3 0 0 0 0 7 0 0 3 0 0
• 0 0 7 0 0 3 3 0
• 0 0 7 7 0 0 3 0
• 0 0 0 7 7 0 0 0
• 0 0 0 0 7 7 7 7
• D) 7 7 7 7 7 7 0 0 0 0 3 0 0 7 0 0
• 0 0 3 0 0 7 7 0
• 0 0 3 3 0 0 7 0
• 0 0 0 3 3 0 0 0
• 0 0 0 0 3 3 3 3
• E) 3 3 3 7 7 7 0 0 0 0 3 0 0 7 0 0
• 0 0 3 0 0 7 7 0
• 0 0 3 3 0 0 7 0
• 0 0 0 3 3 0 0 0
• 0 0 0 0 3 3 3 3

Definitions:

Binomial Distribution

A probability distribution that represents the number of successes in a set number of independent binary (success/failure) experiments.

Consecutive Trials

Successive attempts or tests carried out to achieve a particular result, where each trial follows the previous one without interruption.

Possible Outcomes

Refers to all the potential results that could occur from a specified event or experiment.

Binomial Random Variable

A random variable that has only two possible outcomes, typically described as success and failure, in a series of experiments.
