Implement a system for calculating rewards based on recommendations of customers.
A company is planning a way to reward customers for inviting their friends. They're planning a reward system that will give a customer points for each confirmed invitation they played a part into. The definition of a confirmed invitation is one where an invited person accepts their contract. Inviters also should be rewarded when someone they have invited invites more people. The inviter gets (1/2)^k points for each confirmed invitation, where k is the level of the invitation: level 0 (people directly invited) yields 1 point, level 1 (people invited by someone invited by the original customer) gives 1/2 points, level 2 invitations (people invited by someone on level 1) awards 1/4 points and so on. Only the first invitation counts: multiple invites sent to the same person don't produce any further points, even if they come from different inviters and only the first invitation counts.
Ruby on rails projects using Service Objects https://medium.com/selleo/essential-rubyonrails-patterns-part-1-service-objects-1af9f9573ca1 Projects splitted into services:
- Validator to validate the data.
- Parsing for parsing the upcomming data.
- Errors for handling errors.
- Node for reward chains.
- Calculator for calculating the reward pointing.
