Interview Prompt
Implement a FIFO queue class using two stacks. Support push(x), pop() (return popped value), peek() (return front), empty() (return bool). Test harness passes ops and returns their outputs parallel: None for push, the value for pop/peek, True/False for empty.
Summary
A queue in sheep's clothing.
