This is my solution to the KataGreed Kata from codingdojo.org.

• TDD approach using JUnit with Mockito
• Uses Java 8 lambdas and streams to iterate over each scorer type to calculate overall score
• Uses enum with Java 8 lambdas and streams to determine whether a 'Straight' or 'Three Pairs' has been passed

• Java 8
• Maven

Greed (Dice Game)

Write a class Greed with a score() method that accepts an array of die values (up to 6). Scoring rules are as follows:

A single one (100) A single five (50) Triple ones [1,1,1] (1000) Triple twos [2,2,2] (200) Triple threes [3,3,3] (300) Triple fours [4,4,4] (400) Triple fives [5,5,5] (500) Triple sixes [6,6,6] (600) Note that the scorer should work for any number of dice up to 6.

Four-of-a-kind (Multiply Triple Score by 2) Five-of-a-kind (Multiply Triple Score by 4) Six-of-a-kind (Multiply Triple Score by 8)

Three Pairs [2,2,3,3,4,4] (800)

Straight [1,2,3,4,5,6] (1200)
