That is because there could be an input in which the closing bracket comes first. For example: INPUT: ) Hello ( This will detect a ')' on first iteration then it will search for the index of an opening bracket '('. But since we still have no opening brackets, rindex method will raise an error. https://code.sololearn.com/c5xviIfHKXSy/?ref=app
