    In an adaptive learning system, given a sequence of student responses where 1 represents correct answers and 0 represents incorrect answers, find the largest difference between the number of incorrect and correct answers in any continuous sequence of responses. This analysis helps identify the most significant period of struggle or success in the student's learning journey, enabling appropriate difficulty adjustments.
