create a dataframe from list core interview pattern Pattern
1 problems
Pattern pages help build reusable solving frames. Identify signals first, then explain state, transition, and edge handling.
Recognition Signals
- Check if the candidate uses pandas efficiently.
- Look for the candidate's attention to the specific format in the output.
Solve Flow
- 1. Define the active state/window.
- 2. Update state while preserving invariants.
- 3. Validate with edge-heavy examples.
Common Misses
- Forgetting to explicitly name the columns in the DataFrame constructor.
