Interview Prompt
A life-sciences CRM stores customer accounts in a hierarchy, where each record names its account `id`, the `parent` account it sits under, and the `sales` booked directly to it. For every account, report the combined sales of that account together with every account anywhere below it in the chain.
Summary
Every account carries the weight of all it contains.
