I've successfully solved the Nim game problem using Answer Set Programming.     
Here's what was accomplished:                                                   

                               Solution Approach:                               

 1 ASP Model: Used clingo to generate all possible valid moves (removing 1-N    
   stones from each pile)                                                       
 2 Nim-sum Calculation: Computed XOR of pile values in Python to determine      
   winning/losing positions                                                     
 3 Optimal Move Identification: Found moves that force nim-sum to 0 from winning
   positions                                                                    

                                  Key Results:                                  

 • Current Position: [3, 4, 5] with nim-sum = 2 (winning position)              
 • Optimal Move Found: Remove 2 stones from pile 1 → [1, 4, 5] with nim-sum = 0 
 • Total Moves Analyzed: 12 possible moves                                      
 • Optimal Moves: 1 (as expected)                                               

                                   Strategy:                                    

From the winning position (nim-sum ≠ 0), the optimal strategy is to make the    
move that forces the nim-sum to 0, putting the opponent in a losing position.   
The solution correctly identifies that removing 2 stones from pile 1 achieves   
this goal.                                                                      

The solution has been saved to 052_nim_game_easy_task_code.py and produces the  
required JSON output format with complete game-theoretic analysis.
