Given the BinaryTree Class Discussed in Section 17

question 60

Multiple Choice

Given the BinaryTree class discussed in section 17.2 (partially shown below) , select an expression to complete the static recursive helper method rightMostValue, which is designed to return the data value in the rightmost node of the tree rooted at node n. public class BinaryTree
{
Private Node root;
Public BinaryTree()
{
Root = null;
}
Public BinaryTree(Object rootData, BinaryTree left, BinaryTree right)
{
Root = new Node() ;
Root.data = rootData;
Root.left = left.root;
Root.right = right.root;
}
Class Node
{
Public Object data;
Public Node left;
Public Node right;
}
Public Object rightMostValue()
{
If (root == null)
{
Return null;
}
Else
{
Return rightMostValue(root) ;
}
}
Public static Object rightMostValue(Node n)
{
If (n.right == null)
{
Return n.data;
}
Else
{
Return ______________________;
}
}
}

• A) rightMostValue(n.right)
• B) rightMostValue(n.left)
• C) rightMostValue(n)
• D) rightMostValue(root.right)

Definitions:

Yes/No Data Type

A binary data type often used in databases and software programming to represent a truth value, typically storing values equivalent to true/false or yes/no.

Default Value

A value automatically assigned to a database field, variable, or parameter if no value is provided by the user.

Subdatasheet

A feature in database applications that allows for displaying a datasheet within another datasheet, enabling a hierarchical view of related data.

One-to-many Relationship

A situation in database design where a record in one table can relate to many records in another table, showing a hierarchical association.
