Question 1
5 people (Layla, James, Jordan, William, Yuki) live on floors 1 to 5, one person per floor.
Based on these clues:
• William and Yuki live on consecutive floors
• William lives immediately below Layla
• Layla and Jordan are exactly 2 floors apart
On which floor does William live?
The unique arrangement (floor: person) is: {1: 'Yuki', 2: 'William', 3: 'Layla', 4: 'James', 5: 'Jordan'}.
