Question 1
4 people (Haruki, Jay, Sunil, Loki) live in a 7-floor building (floors 1 to 7). Not all floors are occupied.
Based on these clues:
• Floor 4 is vacant
• Jay and Sunil are exactly 2 floors apart
• Loki lives on the bottom floor
• Haruki lives on the top floor
• Jay does not live on floor 3
On which floor does Loki live?
The unique arrangement (floor: person) is: {1: 'Loki', 3: 'Sunil', 5: 'Jay', 7: 'Haruki'}.
