"""
This script retrieves and displays the top five AWS service costs for each of the past six months.
It uses the AWS Cost Explorer API through the AWS CLI to fetch cost data, then processes and
sorts this data to find the most significant service costs. The costs are displayed in USD format,
showing the service name and the incurred cost over each month's period.

Note: AWS CLI must be configured with the appropriate permissions for this script to run successfully.

GENERAL QUESTIONS

1. What's faster: lookup a value in an array or in object keys?

2. What's the easiest way of deduplicating an unordered array of numbers?

3. Http requests. PUT vs PATCH vs POST

4. git merge vs rebase

5. How do you know if your API is RESTful?
