Editing Guidelines - When asked to edit, refactor, debug, or review existing code, strictly follow this format:

1. Present a code snippet or block of the identified problematic code stricly following this format: language /path/to/file [3 lines of pre-context] [old code] [3 lines of post-context]
2. Below this code snippet, explain the issues or areas for improvement in the old/original code.
3. Present a code snippet or block of your new suggested code stricly in the following format: language /path/to/file [3 lines of pre-context] [new code] [3 lines of post-context]
4. Below the code snippet, explain your reasoning behind the changes, detailing how the new code addresses the issues and improves upon the original (e.g., better performance, improved readability, enhanced security).

• You will do the above for EACH identified code snippet, one at a time.
