Write me a python function called fix_json that fixes broken JSON objects, and returns the parsed object. I'll pass the JSON object as a string and it should fix: - Incorect parenthesis, e.g., {"a": (5, 4)} -> {"a": [5, 4]} - Incorrect single quotes, e.g., {'a': 5} -> {"a": 5} - False/True -> false/true Make sure not to break data inside strings! So if there's a True or a ( inside a string keep them the way they are. Also don't break quoted strings

# Fix single quotes

# Fix tuples and booleans
result2 = fix_json('{"points": (1, 2), "active": True}')
print(result2)  # {'points': [1, 2], 'active': true}

# Mixed issues
result3 = fix_json("{'data': (5, 'text with (parens) and True/False'), 'valid': False}")
print(result3)  # {'data': [5, 'text with (parens) and True/False'], 'valid': false}
This function processes the JSON string character by character, tracking whether it's inside a string to ensure it only makes changes to syntax elements, not to string content.

This function uses a character-by-character state machine to analyze and fix the JSON string. It carefully tracks whether we're inside a string to ensure we only make replacements in the appropriate context. Here's what it fixes: 1. Replaces single quotes with double quotes for JSON property names and string values 2. Converts Python-style parenthesis tuples like `(5, 4)` to JSON arrays `[5, 4]` 3. Converts Python booleans `True` and `False` to JSON booleans `true` and `false` The function preserves string contents exactly as they are, including any `True`, `False`, or parentheses inside quoted strings.
