    Design an algorithm to analyze a student's learning pattern sequence and find the learning segment with the greatest imbalance between mastered concepts (1s) and concepts needing reinforcement (0s). This analysis will help identify the most critical periods where curriculum adjustments are needed, by calculating the maximum difference between successful completions and areas needing support in any continuous period of the student's learning journey.
