Interview Prompt
We're replaying a stream of stack commands against a last-in, first-out stack: push a value, pop the top, peek at it, check whether the stack is empty, or ask for the smallest value currently on it, each encoded as a list with the command name first like `['push', 5]` or `['min']`. Run the commands in order and return one result per command, and make the smallest-value lookup stay fast no matter how many pushes and pops came before it.
Summary
Push, pop, peek. The basics that break people.
