I've successfully solved the DONALD + GERALD = ROBERT cryptarithmetic puzzle    
using Answer Set Programming with the clingo Python API.                        

                                Solution Found:                                 

 • D=5, O=2, N=6, A=4, L=8, G=1, E=9, R=7, B=3, T=0                             
 • Equation: 526485 + 197485 = 723970 ✓                                         

                           Implementation Highlights:                           

 1 ASP Model Design:                                                            
    • Used choice rules to assign each letter exactly one digit                 
    • Enforced bijection constraint (each digit used exactly once)              
    • Prevented leading zeros for D, G, and R                                   
    • Modeled column-wise addition with carry propagation                       
 2 Arithmetic Constraints:                                                      
    • Encoded 6 columns of addition from right to left                          
    • Each column constraint checks: digit1 + digit2 + carry_in = result +      
      10*carry_out                                                              
    • Carries are binary (0 or 1) and chosen by the solver                      
 3 Solution Extraction:                                                         
    • Extracted digit assignments from answer set                               
    • Verified arithmetic correctness                                           
    • Formatted output as required JSON                                         

The solution is saved in 014_cryptarithmetic_hard_task_code.py and executes in  
well under 10 seconds.
