Insert two new points, $M$ at $(1,1)$ and $N$ at $(10,10),$ in that order, in to the point quadtree. Mark the proper nodes on the tree where these two new points should belong.

Also, there are two points, $x$ and $Y,$ on the map that are represented as nodes in red in the quadtree. Mark the approximate places where these two points should belong on the map. $[$ Draw Viaual Example Please$]$
