Person {
int name;
int id

CheckPoint {
	DoublyLinkedList first;
	DoublyLinkedList last;
	Map<String, DoublyLinkedList> personToDLL; // person id to node
	public CheckPoint() {
		personToDLL = new HashMap<>();

DoublyLinkedList {
	Person person;
	DoublyLinkedList prev;
	DoublyLinkedList next;


Map<String, CheckPoint> map; // checkPoint name to Object map
String HighestCheckPointReported; // to store the highest checkPoint that is reported;

Logic :

Everytime a person crosses the checkPoint(CP2)
1. Go to previous check point(CP1) if exists, get the node and delete from the list and map;
update the first and last node in checkPoint accordingly;
add the node to the current checkPoint based on the last node;
add to the map as well;

if previous check point doesnt exists, create the person the insert into the list; add this to the map; in current checkPoint

Everytime update the HighestCheckPointReported if it is higher

To get the rank

Iterate from the HighestCheckPointReported to the lowestCheckPoint[first node in each CheckPoint object would help to find the order]
