Armstrong Service

This is a simple Drools rule example using Spring boot REST API's. Dependency details can be found in build.gradle file. Cucumber BDD is used for unit and rest level testing.

Overview

Analyzes a given integer and determines whether or not it is an Armstrong number. Final decision is made using simple Drools rule.
An Armstrong number is an n-digit number that is equal to the sum of the n'th powers of its digits. E.g. 153 = 1^3 + 5^3 + 3^3
