Interview Prompt
A lookup service keeps its record IDs as a sorted list of integers and resolves a query to the slot it occupies. Return the index of `target` in `nums`, or -1 when it is absent. The list can be large and the ordering is guaranteed, so the lookup should not have to scan every element.
Summary
Every guess cuts the problem in half.
