This seems simple, but I would like to do this as efficiently as possible. Effectively, I am interested in the points that are The most northeastern point. Given an Array like: [[10,2],[0,2],[1,10],[1,0],[2,3],[5,2],[7,2],[7,3],[3,8],[6,1]] My idea is to use X**2+y**2 to calculate, I don't know if my idea is correct. Is Get point with highest and lowest x and y value in python similar to this one? My expression seems a bit rough. I defined the first index of the list as latitude and the second index as precision, that is, [[b,l],[b,l]]. It seems that X+Y is the most northeastern coordinate? I am not sure if my thinking is correct. Continue reading...
