Sum Distances To Origin With Pattern Matching Compared To Java Assignment

Motivation

Compare implementations in Java and SML to highlight the crispness of type inference and pattern matching.

Previous Warmup

This warmup is a variation of the Sum Distances To Origin with Functions warmup.

Background

SML

Math.sqrt(x)

Java

Math.sqrt(x)

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

Math.sqrt(v)

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

SML

file:	src/main/sml/warmup_sum_distances_to_origin_pattern/sum_distances_to_origin.sml
functions:	sum_distances_to_origin

Math.sqrt(v)

fun sum_distances_to_origin(xys : (real * real) list)

Test

Java

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