Given the MileageTrackerNode class, complete main in the MileageTrackerLinkedList class to insert nodes into a linked list using the insertAfter method. The first user-input value is the number of nodes in the linked list. Use the printNodeData method to print the entire linked list. DO NOT print the dummy head node. Ex. If the input is

In this case, Change the head of the node to the next node of current head. Free the memory of replaced head node. Case 2 The position is greater than 0 but less than the size of the list, i.e. in the middle or last, except at head . In this case, Find previous node of the node to be deleted.

Now that we can add nodes into our List, we must find a way to display or print all nodes of the list to the screen, the code for this comes from the display function as shown below. Prints every element in the list to screen public void display Node currNode head First node is set to head for int i 0 currNode ! null i loop till currNode is not null Display the

Linked List is one of most used and common data structures made of a sequence of nods. Each node contains a value and a pointer to the next node in the sequence. The quotheadquot node points to the first node of the sequence and the last node of the sequence point to NULL for singly-linked list.

Your implementation does not allow for an empty list. It's a bit odd to only have the constructor which takes a node value. You should probably implement the List interface.. You should look into generics instead of hard-coding your list to only take ints.. It looks like from looking at insert that you are trying to create an ordered linked list. However, append does not.

public void insertAtFrontPeopleNode headNode, PeopleNode currNode currNode.nextNodeRef headNode.nextNodeRef headNode.nextNodeRef currNode Here is a visual of what is happening. It starts like this head -gt person1 -gt person2 -gt person3 First we make the new node point to the node that head is already pointing to

Time Complexity On, where n is the number of nodes in the linked list. Auxiliary Space O1 Expected Approach - 2 Using Single Traversal - On Time and O1 Space The idea is based on the tortoise and hare algorithm which uses two pointers, slow_ptr and fast_ptr to traverse the list. Here, slow_ptr moves one step at a time while fast moves two steps.

TLDR Recommendations to simplify the implementation of an Iterator's remove method The iterator is of class DLListIterator of generic type ltEgt Doubly-LinkedList Iterator and Implements java.util.Iterator.
