Swing Data Coding Challenge

Swing Data Coding Challenge

This repository contains my proposed solution for the Swing Data Coding Challenge.

Repository Structure

In addition to this README, the test data supplied with the exercise, and files used by the Gradle build system, this repository contains the following files:

• The implementation for the four methods described in the challenge is located in src/main/java/swingdata/Analysis.java.

• src/main/java/swingdata/SwingData.java contains the data structure representing the data for a swing.

• src/test/src/test/java/TestSwingDataAnalysis.java contains some unit tests of the four requested functions.

Build Instructions

To build:

$ ./gradlew build

on UNIX platforms, or

C:> gradlew.bat

on Windows.

Testing

To run the unit tests:

$ ./gradlew test

Bonus Question

I don't remember a lot from physics classes, but I do remember conservation of momentum, which says that the impact of the ball on the bat will cause the bat to slow down. I would expect this to be reflected in the accelerometer data. Just from eyeballing the CSV, it looks like the accelerometer values peak around index 876, so I think that's where the impact is.
