    Given a binary pattern representing a patient's post-discharge behaviors where 1s indicate compliant behaviors and 0s indicate non-compliant behaviors, develop a function that identifies and flags the most critical unaddressed behavior (leftmost 0) for immediate intervention. The function should convert this highest-priority unaddressed behavior to addressed (changing leftmost 0 to 1) to help reduce readmission risk.
