I have a main.py file with three functions that need to be implemented for the Diffie-Hellman key exchange: 1. `private_key(p)` - generates a private key greater than 1 and less than p 2. `public_key(p, g, private)` - calculates public key A = g^a mod p 3. `secret(p, public, private)` - calculates shared secret s = public^private mod p The tests.py file shows exactly what these functions should do. Based on the problem description, I need to implement these three functions. The main.py file is the only file that needs to be modified. Let me signal that I've found the files that need to be fixed. 2025-12-13 04:54:06,081 - agent - INFO - [FINISH_FIND_FILES_TO_MODIFY] About to execute 1 tool call(s): ['finish_find_files_to_fix'] 2025-12-13 04:54:06,081 - agent - INFO - [FINISH_FIND_FILES_TO_MODIFY] Tool arguments: [ { "files": [ "main.py" ] } ] 2025-12-13 04:54:06,081 - agent - INFO - [FINISH_FIND_FILES_TO_MODIFY] Combined observation: ['main.py'] 2025-12-13 04:54:06,082 - agent - INFO - [GENERATE_INITIAL_SOLUTION] Starting solution generation 2025-12-13 04:54:06,083 - agent - INFO - [GENERATE_INITIAL_SOLUTION] Starting solution generation 2025-12-13 04:54:08,245 - agent - INFO - [GENERATE_INITIAL_SOLUTION] Requesting code generation from model 2025-12-13 04:54:09,378 - agent - INFO - [GENERATE_INITIAL_SOLUTION] Requesting code generation from model HEAD is now at e467245 Initial commit HEAD is now at e467245 Initial commit HEAD is now at e467245 Initial commit 2025-12-13 04:54:22,047 - agent - INFO - [GENERATE_INITIAL_SOLUTION] Starting solution generation 2025-12-13 04:54:22,047 - agent - INFO - attempt_idx :1 completed 2025-12-13 04:54:22,047 - agent - INFO - Initial solution in process_create_task for 1: main.py import random def private_key(p): # Edge Case: p <= 1, no valid private key can be generated if p <= 2: raise ValueError("p must be greater than 2 to generate a valid private key") # Edge Case: p == 2, only valid private key is 1, but must be greater than 1 and less than p # This would be an invalid case as no number can be both > 1 and < 2 return random.randint(2, p - 1) # Handled Edge Cases: p <= 2 def public_key(p, g, private): # Edge Case: p <= 1, invalid prime if p <= 1: raise ValueError("p must be greater than 1") # Edge Case: private key outside valid range (≤ 1 or ≥ p) if private <= 1 or private >= p: raise ValueError("private key must be greater than 1 and less than p") # Edge Case: negative or zero inputs for g if g <= 0: raise ValueError("g must be positive") return pow(g, private, p) # Handled Edge Cases: p <= 1, private key outside valid range, negative or zero g def secret(p, public, private): # Edge Case: p <= 1, invalid prime if p <= 1: raise ValueError("p must be greater than 1") # Edge Case: private key outside valid range (≤ 1 or ≥ p) if private <= 1 or private >= p: raise ValueError("private key must be greater than 1 and less than p") # Edge Case: negative or zero inputs for public key if public <= 0: raise ValueError("public key must be positive") return pow(public, private, p) # Handled Edge Cases: p <= 1, private key outside valid range, negative or zero public key 2025-12-13 04:54:22,047 - agent - INFO - Found a feasible solution!!!
