Background
The distance of a point (x,y) from the origin:
Basis Library
Code To Implement
sum_distances_to_origin
| file: | src/main/sml/sum_distances_to_origin_fun/sum_distances_to_origin.sml |  |
| functions: | sum_distances_to_origin |
A list of tuples xys is passed to sum_distances_to_origin. Evaluate to the sum of the distances from each point (x,y) in the list to the origin.
fun sum_distances_to_origin(xys : (real * real) list)
For example, if the list is [(3,4), (5,12)] then calling sum_distances_to_origin with that list would evaluate to 18 (since 5 + 13 is 18).
