Interview Prompt
The platform team is doing a quick capacity check. Compare the number of active user accounts against the number of infrastructure nodes deployed in us-east-1. If active accounts outnumber us-east-1 nodes, return 'More active'; otherwise return 'More us-east-1'.
Summary
Being in the region and being active are two very different things.
