                                    Summary                                     

I've successfully completed the Zebra Puzzle task using Answer Set Programming  
(ASP) with the clingo Python API. Here's what was accomplished:                 

                               Solution Overview                                

The program correctly solves Einstein's Riddle and determines that the German   
owns the zebra.                                                                 

                               Complete Solution:                               

 1 House 1: Yellow, Norwegian, Water, Dunhill, Cats                             
 2 House 2: Blue, Dane, Tea, Blends, Horse                                      
 3 House 3: Red, Brit, Milk, Pall Mall, Birds                                   
 4 House 4: Green, German, Coffee, Prince, Zebra ✓                              
 5 House 5: White, Swede, Beer, Blue Master, Dog                                

                            Implementation Approach:                            

 • Choice Rules: Each house gets exactly one of each attribute type             
 • Uniqueness Constraints: Each attribute value appears exactly once across all 
   houses                                                                       
 • Logical Constraints: All 15 puzzle constraints encoded as integrity          
   constraints                                                                  
 • Adjacency Handling: Used arithmetic expressions (H1-1, H1+1) for "next to"   
   relationships                                                                

All 15 constraints were verified and the solution is correct. The code has been 
saved and is ready to use.
