    Given a student's assessment history represented as a sequence where 1 indicates a correct answer and 0 indicates an incorrect answer, find the maximum difference between the number of incorrect and correct answers in any continuous segment of their performance record. This analysis will help identify the most significant learning gaps or strongest areas of mastery in the student's assessment history.
