                                    Summary                                     

I've successfully completed the Tower of Hanoi puzzle using Answer Set          
Programming (ASP) with the clingo Python API. Here's what was accomplished:     

                              Solution Highlights:                              

 1 Optimal Solution Found: The solver found the optimal solution with exactly 15
   moves (2^4 - 1 = 15 for 4 disks)                                             
 2 ASP Model Features:                                                          
    • Temporal planning with time steps 0-15                                    
    • Sequential action modeling (exactly one move per timestep)                
    • Frame axioms for state persistence                                        
    • State exclusivity constraints (disk can't be on two pegs)                 
    • Precondition checking (can't place larger disk on smaller)                
    • Optimization to minimize total moves                                      
 3 Verification: The solution was verified to:                                  
    • Follow all Tower of Hanoi rules                                           
    • Successfully move all disks from peg A to peg C                           
    • Maintain proper disk ordering (largest to smallest)                       
 4 Output: Properly formatted JSON with all 15 moves in sequence                

The final code has been saved to 026_tower_of_hanoi_easy_task_code.py and       
produces the correct optimal solution when executed.
