Question 1
6 people (Dakota, Hazel, Hikari, Barbara, Jessica, Kaito) live in a 8-floor building (floors 1 to 8). Not all floors are occupied.
Based on these clues:
• There is exactly one floor between Hazel and Barbara
• Floor 3 is vacant
• Jessica lives on the bottom floor
• There are exactly two floors between Dakota and Kaito
• Jessica and Kaito live on consecutive floors
• Hazel lives immediately above Hikari
On which floor does Jessica live?
The unique arrangement (floor: person) is: {1: 'Jessica', 2: 'Kaito', 5: 'Dakota', 6: 'Barbara', 7: 'Hikari', 8: 'Hazel'}.
