This pattern is crafted to match the given targeted items exactly. It specifically accounts for these requirements: \n1. Matching 'jane_smith+regex@sub-domain.com?ext=123': This can be done by specifying the exact string, including special characters.\n2. Capturing '(123) 456-7890 ext. 101': Brackets, spaces, numbers, and the word 'ext.' with a number at the end are matched.\n3. Supporting valid date formats '02/14/2023' and '2023-02-14': Separate alternatives in the pattern cover these formats.\n4. For '192.168.001.001': This IP address is matched directly as written, including leading zeroes.\n5. Matching file path 'C:\\Users\\Name\\file(backup).txt': Backslashes and parentheses are escaped properly to match the literal occurrence. \nThese have been combined carefully to not match non-target distractor strings.
