Question 1
5 people (Divya, Hiroshi, Yusuf, Pankaj, Kenji) live in a 7-floor building (floors 1 to 7). Not all floors are occupied.
Based on these clues:
• Floor 6 is vacant
• Hiroshi and Kenji are exactly 1 floor apart
• Divya and Pankaj are exactly 2 floors apart
• Hiroshi lives on floor 1
• There are exactly two floors between Yusuf and Pankaj
• Pankaj lives on floor 7
On which floor does Kenji live?
The unique arrangement (floor: person) is: {1: 'Hiroshi', 2: 'Kenji', 4: 'Yusuf', 5: 'Divya', 7: 'Pankaj'}.
