Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the logic errors pattern
The wrong operator, an inverted condition, a formula the right way round but backwards.
What went wrong: re.match() only checks for a match at the very beginning of the string. Digits appearing after non-digits are ignored.
The fix: Use re.search() to scan the entire string: re.search(r'\d+', text)
Remember: In Python regex, re.match() checks only the string start, while re.search() scans the whole string.
The pattern behind it: logic errors.
