Background
The distance of a point (x,y) from the origin:
Basis Library
Code To Implement
sum_distances_to_origin
Fall 2022 Note: if attempted without pattern matching, you may receive an unresolved flex record error:
../../../main/sml/warmup_sum_distances_to_origin/sum_distances_to_origin.sml:4.2-21.56 Error: unresolved flex record (need to know the names of ALL the fields
in this context)
type: {1:real, 2:real; 'Z}
this can be solved by using pattern matching or specifying the type of the parameter xys:
fun sum_distances_to_origin(xys : (real * real) list)
| file: | src/main/sml/warmup_sum_distances_to_origin/sum_distances_to_origin.sml |  |
| functions: | sum_distances_to_origin |
fun sum_distances_to_origin(xys : (real * real) list)
Test
