Interview Prompt
Implement a class MinStack supporting push(x), pop(), and get_min(). All three operations must run in O(1) time. get_min returns the current minimum element in the stack without removing it. (The visible test harness passes operation names and arguments as parallel lists and expects a parallel list of return values: None for push/pop, the min value for get_min.)
Summary
The stack remembers the best it ever saw.
