    Given a student's practice test performance as a sequence where 1 represents correct answers and 0 represents incorrect answers, find the section of consecutive questions that shows the largest difference between the number of incorrect and correct responses. This difference will be used to determine the most significant learning gap and adjust the difficulty level accordingly.
