Question

Problem 12 (10pts) Stack memory is implemented as a stack data structure. A) Provide the sequence of push and pop operations on stack memory when the display method (provided below) is called with curr = root on the BST shown below. When specifying a push, provide the Node parameter by indicating the value it stores. private void display(Node curr){ if(curr != null){ display(curr.left); display(curr.right); System.out.print("+ curr.data); } } B) What is printed out by the display method above when run on the BST shown above (curr=root)? The node class is implemented in the typical way (has Node left, right, and int data). Problem 13 (10 pts): What is the worst case time complexity for bucket sort? Explain why and provide an example. When would you use bucket sort over any of the compare based sorting algorithms?

Stack memory is implemented as a stack data structure.
A) Provide the sequence of push and pop operations on stack memory when the display
method (provided below) is called with curr = root on the BST shown below. When
specifying a push, provide the Node parameter by indicating the value it stores.
private void display(Node curr){
if(curr != null){
display(curr.left);
display(curr.right);
System.out.print("+ curr.data);
}
}
B) What is printed out by the display method above when run on the BST shown above
(curr=root)? The node class is implemented in the typical way (has Node left, right, and
int data).
Problem 13 (10 pts):
What is the worst case time complexity for bucket sort? Explain why and provide an
example. When would you use bucket sort over any of the compare based sorting
algorithms?
