This task involves generating the rest of a sequence of brackets, ensuring that the sequence is properly closed. The primary challenge is keeping track of the opening and closing brackets and ensuring that the sequence is properly balanced.

Analyzing the Task:
1. Understanding the Bracket Sequence: Understanding the sequence of brackets and the rules for closing them is essential.

2. Parsing the Input: Parsing the input text to extract the sequence of brackets.

3. Maintaining a Stack: Maintaining a stack of opening brackets and closing them in the correct order is crucial.

4. Handling Varied Input: The input text may vary in format and content, requiring flexible parsing to extract the necessary information.

Constructing the Code Prompt:
1. Extracting the Bracket Sequence: The first step is parsing the input text to extract the sequence of brackets.

2. Initializing a Stack: Create a stack to keep track of the opening brackets.

3. Updating the Stack: Iterate over the parsed bracket sequence, update the stack referring to the each bracket.

4. Generating the Rest of the Sequence: Generate the rest of the sequence by popping the stack and outputting the corresponding closing bracket.

5. [Important] Handling the Stack: Handle the stack properly to ensure that the sequence is properly balanced.

6. Returning the Final Answer: Return the final answer as a string of closing brackets seperated with a space.
