4 people (Shweta, Robin, Aisha, Haruki) live in a building with floors 1 to 4. They recently moved between floors.
Based on these clues:
• Initially, Shweta lived on floor 1
• Initially, Robin lived on floor 2
• Initially, Aisha lived on floor 3
• Initially, Haruki lived on floor 4
• Shweta moved 2 floors up
• Robin moved 2 floors up
• Aisha moved 2 floors down
• Haruki moved 2 floors down
• Haruki lives on floor 2
• Aisha lives immediately below Haruki
• There is exactly one floor between Robin and Haruki
After the moves, on which floor does Aisha live?
The unique arrangement (floor: person) is: {1: 'Aisha', 2: 'Haruki', 3: 'Shweta', 4: 'Robin'}. Initial state: {'Shweta': 1, 'Robin': 2, 'Aisha': 3, 'Haruki': 4}.
