Good day,

I have an array of points which represent points in a 2d map.

I need to find the topleft, topright, bottomleft, bottomright points in that map. However, there are alot of points in between and out. What is the easiest way I can do this? I could find the value with the highest y, but that might not have the highest x and so on.

Just letting me know the logic would be great.

look for : topLeft(min_x,min_y) topRight(max_x,min_y) buttomLeft(max_x,max_y) buttomRight(min_x,max_y)
tha is true if the origin is on the top left and x_axis is horizontal y_axis is vertical
