The Einstein's Puzzle is a well-known logic puzzle. It is often called Einstein's Puzzle because it is said to have been invented by Albert Einstein as a boy. However, there is no known evidence for Einstein's or Carroll's authorship. This puzzle can be modified with various conditions to produce a variety of similar puzzles. For starters, we will solve a simplified version of the puzzle.

There are 5 houses on street which are painted 5 different colors: blue , green , red , white and yellow .
In each house lives a person of a different nationality: Brit , Dane , German , Norwegian and Swede .
These people drink a certain beverage: beer , coffee , milk , tea and water .
Smoke a certain brand of cigarettes: Rothmans , Dunhill , PallMall , Winfield and Marlboro .
They keep a certain pet: cat , bird , dog , fish and horse .

None of the owners have the same pet, smoke the same brand of cigarette, or drink the same beverage.

You are given a set of "relations". Each relation connects two identifiers in the owner relationships. For example: "Norwegian-Dunhill"...
