Background
The distance to the origin for a point (x, y) is:
Is the sqrt required when comparing two points to see which is closest to the origin or can you just determine which point's squared distance is closer?
Basis Library
Option
Code to Implement
file: | src/main/sml/closest_to_origin/closest_to_origin.sml | |
functions: | closest_to_origin |
closest_to_origin
Write a function
fun closest_to_origin(xys : (real*real) list) : (real*real) option =
which returns closest point to the origin, if it exists.
