for the last picture the question is -- shall we have errors when running the code for some linked list? if so, what kind of linked list will trigger errors and what is the error?

09.1 25 Points Implement the method findMin() that finds and returns the minimum value in a linked list. Assume the linked list holds only positive values. You may NOT use or implement helper methods - all your code must be implemented inside the given method. You may NOT use recursion public class Node { public int data; public Node next; } 77 Given a front pointer to the first node in the list. // Returns the minimum value among all integers in the list. // Input list could be empty, returns -1 1f the given linked list is empty public static int findMin (Node front) { 17 COMPLETE THIS. METHOD } Enter your answer here Q9.2 5 Points What is Big O notation for the running time of the findin() method in part 9.1? Give your reasoning process. Enter your answer here 09.3 10 Points Consider the linked list: front -> 2 - 5 - 6 - 1 -> null Assume the Node class from course slides. What is the resulting linked list after the following code snippet runs: = Node prev = null; Node ptr front; while ( ptr.next != null ) { prev = ptr; ptr ptr.next; } Node newNode = new Node(); newNode.item 2; newNode. next null; prev.next = newNode; 09.4 5 Points Read the following code snippet (same as part 9.3); Node prev Node ptr null; front; while ( ptr.next != null ) { prev = ptr; ptr = ptr.next; } Node newNode = new Node () ; newNode.item 2; newNode. next null; prev.next = newNode; Shall we have errors when running the code for some linked list? If so, what kind of linked list will trigger errors and what is the error? Entonces here
