To solve this problem, we need to reformat system requirements given in JSON format into a structured HTML output. The requirements can either be provided as a list of key-value pairs for a single system or as separate specifications for multiple systems (e.g., Windows, Mac, Linux). ### Approach 1. **Check Input Structure**: Determine if the input is a list of key-value pairs for a single system or includes separate specifications for multiple systems. 2. **Parse Requirements**: - If the input includes separate systems (e.g., "Windows", "Mac", "Linux"), parse each system's requirements from an HTML string and extract each list item. - If the input is a single system, directly use the key-value pairs. 3. **Generate HTML Structure**: - For each system, create a `div` element with a heading indicating the system name. - Include a paragraph with "MINIMUM SPECS". - Construct an unordered list and populate it with the parsed requirements. 4. **Construct the Complete HTML Output**: Combine all system requirement sections into a single HTML string without any markdown or additional formatting. ### Solution Code ```python import json def reformat_system_requirements(json_input): # Parse the JSON input data = json.loads(json_input) output_html = [] for item in data: if 'system' in item: # Handle case where each item is for a different OS system = item['system'] req_html = item['requirement'] # Parse the requirement HTML to extract list items # This is a simplified approach using string splitting li_start = '

' li_end = '

' items = req_html.split(li_start)[1:-1] # Exclude the first and last which are parts before first li and after last li # Process each item to extract span and text requirements = [] for li in items: span_start = '' span_end = '' content = li.split(span_start) if len(content) < 2: continue # skip if span not found key_part = content[1].split(span_end)[0].strip() value_part = li.split('')[1].split(li_end)[0].strip() requirements.append((key_part, value_part)) # Create the HTML div for this system div_html = f'

' output_html.append(div_html) else: # Handle single system case, assuming all items are for the same system if len(output_html) == 0: # Initialize the div div_html = '' output_html.append(div_html) # Combine all parts final_html = ''.join(output_html) return final_html # Example usage: json_input = '[{"OS":"Windows XP or Windows Vista"},{"Processor":"1.8 GHz"},{"Memory":"512MB RAM (1 GB recommended)"},{"Graphics":"3D graphics card compatible with DirectX 8 (compatible with DirectX 9 recommended)"},{"Hard Drive":"2GB"},{"Additional":"Mouse, Keyboard"}]' print(reformat_system_requirements(json_input)) ``` ### Explanation The code provided converts the input JSON into the required HTML format. It handles both single system specifications and multiple systems (e.g., Windows, Mac, Linux) separately. The approach involves: - Parsing the input JSON to determine if it includes separate systems or a single system. - For each system, constructing a `div` element with a heading, a "MINIMUM SPECS" paragraph, and an unordered list of requirements. - Extracting and formatting each requirement correctly, whether it's a simple key-value pair or part of an HTML string. This method ensures the output is clean, well-structured, and adheres to the specified guidelines.
