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

there is a picture of class attatched

define QTNODE H finclude &found) : void dump ); iterator begin ): iterator end ): BBox m bounds: // The bounding box for this node f leaf node (?.e., no kids), m-point, n..data hold the Point m-point : int m, data; // // actual poine and data value the user inserted /You must add data member (s) to store poincers to chald QqNode ' define QTNODE H finclude &found) : void dump ); iterator begin ): iterator end ): BBox m bounds: // The bounding box for this node f leaf node (?.e., no kids), m-point, n..data hold the Point m-point : int m, data; // // actual poine and data value the user inserted /You must add data member (s) to store poincers to chald QqNode
