Use your head

You have the chance to take your room in a hotel where four of the most intelligent people who ever lived are staying. The hotel has five rooms and a small restaurant with five tables. Each person has a rank that shows their level of intelligence compared to the others. The person with the first rank is said to be the Head, and he or she is not you. Rooms, as well as tables, are successively numbered from 1 to 5 in a way that each person lives in a room and eats on a table different in number from their rank. To avoid confrontation, people with successive ranks are neither allowed to live in rooms next to each other nor to eat on tables next to each other. The four people in residence are: Confucius, Marie Curie, Albert Einstein, and Scheherazade. To take your room in the hotel, you must work out your rank, table number and room number knowing that:

• Scheherazade doesn't eat on the fifth table.
• Einstein is not the Head.
• Scheherazade has exactly the middle rank between Marie Curie and you.
• Einstein is more intelligent than Scheherazade.
• Confucius eats on a table next to that of Einstein.
• Marie Curie does not eat on a table with the same number as her room number.
