Multiple choiceMediumchapter-16-curatedpremiumperformancedata-structure-choice

Keep data structure choice implicit so the script stays short and hope the next engineer infers the rule.Solve the symptom with comments only and avoid changing the code shape around data structure choice.Delay clarity until production traffic reveals the edge case and then patch it under pressure.Pick the shape that matches membership checks, ordering needs, update patterns, and read frequency.

Answer and explanation

Correct answer

D. Pick the shape that matches membership checks, ordering needs, update patterns, and read frequency.

Why

Pick the shape that matches membership checks, ordering needs, update patterns, and read frequency. That is the stronger engineering move because this is interview-friendly because it connects algorithmic judgment to everyday python code. Sticking with the first convenient structure can add avoidable cost everywhere else.
