Once upon a time, there was a little robot name Grid. He lived in a world where everything was represented by a unique hash code. One day, Grid's head started to malfunction and he couldn't think clearly.
He went to the heap of spare parts to find a new head. After searching through the pile, he found the perfect head and installed it.
With his new head, Grid was able to think clearly again and continue his adventures in the world of hash codes. The end.

3. What was special about the new head Grid found in the heap?
4. How did Grid feel after getting a new head?
