Group Warmup

Motivation

Compare implementations in Java and SML to highlight what pattern matching provides.

Code To Implement

Java

class: SumDistancesToOrigin.java Java.png
methods: sumDistancesToOrigin
package: distance.warmup
source folder: src/main/java

Math.sqrt(v) 

public static double sumDistancesToOrigin(ImList<ImTuple2<Double, Double>> xys)

SML

file: src/main/sml/warmup_sum_distances_to_origin/sum_distances_to_origin.sml Smlnj-logo.png
functions: sum_distances_to_origin

Math.sqrt(v) 

fun sum_distances_to_origin(xys)

Test

Java

class: SumDistancesToOriginTestSuite.java Junit.png
package: distance.warmup
source folder: src/test/java

SML

file: unit_test_sum_distances_to_origin.sml
source folder: src/test/sml/warmup_sum_distances_to_origin
