Inensus - Transaction Handling

Hi! Are you ready to join our team working on an innovative and exciting project?

For the test assignment, we would like you to create a basic transaction processing unit that is responsible to cover different types of debts and generating energy.

How to prioritize payments?

The transaction processor prioritizes different types of payments as following; 1- Covering appliance rate debts 2- Covering tariff fixed costs 3- Generating electricty with the rest amount

Helpful notes:

We love the Service Layer and testing, so don't hesitate to use it :) .

• If the sent amount can not cover the debts, just pay as much as you can.
• The energy could be sold as chunks. That means, if the amount can not cover the whole unit; 0.x ( 1<=x<=9 with only one decimal) units could be generated.
• When the rest amount (after all debts are paid) can not fit 0.x; Please topup the amount to the next 0.x.
