Background
SML
Java
Code To Implement
Java
Note: you will need to complete the ImList<E> exercise before testing the Java portion of this assignment.
class: | SumDistancesToOrigin.java | ![]() |
methods: | sumDistancesToOrigin | |
package: | distance.warmup | |
source folder: | src/main/java |
public static double sumDistancesToOrigin(ImList<ImTuple2<Double, Double>> xys)
SML
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
Java
class: | SumDistancesToOriginTestSuite.java | ![]() |
package: | distance.warmup | |
source folder: | src/test/java |
SML
source folder: | src/test/sml/warmup_sum_distances_to_origin |
