a monkey , giraffe , elephant and a tiger are living in 4 cages as its described in the drawing in this link: http://img397.imageshack.us/my.php?image=16670586ic0.gif which one of this arguments doesn't settle with with the other three arguments? 1.the giraffe is living between the floor of the elephant and the floor of the monkey 2.the tiger is not living above the elephant. 3.in a floor which is located between the floor where lives the elephant and the floor where lives the giraffe ,lives only one animal. 4. in a floor which is located between the floor where lives the monkey and the floor where lives the tiger ,lives only one animal. i don't know from where to start so i started from top to bottom from 1 i can understand that the monkey and the elephant are separated . one of them lives in the first floor and the other lives in the third floor the giraffe lives in the second floor from 2 i can understand that in order for the tiger not to be above the elephant and without crossing the 1st argument ,we need to put the elephant in the 3rd floor and the tiger into one of the cages in the first floor. and the remaining places in the first floor goes to the monkey but in this way it crashes with both arguments 3 and 4 what is the algorithm for solving such a question?
