- Is the limit of the MST $$$O(n\sqrt{q})$$$ just like Mo's algo, where all $$$x,y$$$-s of $$$q$$$ points lies in interval $$$(1,n)$$$
- How to extend it into high-dimension linear space, how to define the $$$45^\circ$$$ in the algo
- If change the Manhattan Distance to Euclidean Distance, is the $$$45^\circ$$$ correct, how to proof
