Pattern pages help build reusable solving frames. Identify signals first, then explain state, transition, and edge handling.

Recognition Signals

  • They want you to recognize a per-group boundary comparison, not a global cheapest-versus-expensive check.
  • They are testing whether you can preserve row-level quantity after aggregating price by store.

Solve Flow

  1. 1. Define the active state/window.
  2. 2. Update state while preserving invariants.
  3. 3. Validate with edge-heavy examples.

Common Misses

  • Comparing the minimum quantity and maximum quantity instead of the quantity attached to the minimum and maximum price.
