i need help on a computer science project. Below is the link for the project

https://userpages.umbc.edu/~park/cs341.s18/projects/proj3.shtml

this project is on implenting a quadtree. i have a fair understanding on how to go about it. however there is a file called "Qnode" that has an iterator class that needs to implemented. can someone help me with the implentation of the iterator class? would really apprciate it

#include "Point." finclude "BBox.h" tdefine OT NUM KIDS 4 class QTNode public: class iterator t public: iterator ); bool operator-= (const QTNode :iterator &other); bool operator! (const QTNode: :iterator &other): iterator &operator++0 iterator operatort (int dummy): // Postfix: "it++ QTNode *soperator // Prefix: e.g. "+tit" private: // Add data members here to record state of current iterator position OTNode) bool add (const Point spt, int data): // actually, add/replace bool remove (const Point &pt, bool &empty): void dump () : iterator begin): iterator end 0: BBox a bounds: // The bounding bcx For thia r point m-point : // If leaf node?.e., no kids), m_point , mi data hold the // actuel point and data vazue the user inserted you must add data member (s) t?"ore pointer# to hild QTNode'a / You CAN ADD AUY OTHER CONSTR AS NEEDED #include "Point." finclude "BBox.h" tdefine OT NUM KIDS 4 class QTNode public: class iterator t public: iterator ); bool operator-= (const QTNode :iterator &other); bool operator!
