Perfect! I have successfully completed the Quantum Nim task using Answer Set    
Programming with the clingo API. Here's what was accomplished:                  


                                Solution Summary                                

Approach:                                                                       

 • Used a hybrid ASP/Python solution where ASP generates all valid moves and    
   Python filters for optimal ones                                              
 • ASP models both standard moves (removing stones) and split moves (Player 1's 
   power)                                                                       
 • Python calculates nim-sum and checks for duplicate pile sizes                

Results:                                                                        

 • Initial nim-sum: 6 (winning position)                                        
 • Found 3 optimal standard moves that lead to nim-sum = 0:                     
    1 Remove 6 stones from pile 0 → [7, 10, 13]                                 
    2 Remove 6 stones from pile 1 → [1, 6, 10, 13]                              
    3 Remove 2 stones from pile 3 → [6, 7, 10, 11]                              
 • Found 0 optimal split moves                                                  

Key Features: ✅ Uses clingo Python API for ASP modeling ✅ Completes in well   
under 10 seconds ✅ Outputs correct JSON format ✅ Handles all constraints (no  
duplicates, nim-sum = 0) ✅ Clean, well-documented code                         

The solution has been saved to 052_nim_game_hard_task_code.py and tested        
successfully.
