Core Components Student Management • Maintains a sorted list of students using a doubly-linked list • Each student has: ID, name, age, and GPA • Supports adding and removing students • Uses merge sort for maintaining sorted order • Implements binary search for efficient student lookup

Course Management • Maintains a sorted list of courses using a doubly-linked list • Each course has: ID, name, and enrollment capacity • Supports adding and removing courses • Uses merge sort for maintaining sorted order • Implements binary search for efficient course lookup

Enrollment System • Manages student-course relationships • Bidirectional linking between students and courses • Supports course enrollment and withdrawal • Maintains enrollment limits per course • Tracks student grades in enrolled courses

Undo/Redo Functionality • Tracks enrollment actions • Supports undoing recent enrollment operations • Allows redoing previously undone actions • Maintains consistency in enrollment states

Key Features • Student operations (add, remove, search) • Course operations (add, remove, search) • Enrollment management • Grade tracking • Course capacity management • Undo/Redo capability • Sorted list maintenance • Performance optimized searching

Data Structures • Doubly-linked lists for students and courses • Stack implementation for undo/redo operations • Binary search implementation for efficient lookups

The system provides a comprehensive solution for managing student enrollments while maintaining data integrity and offering the flexibility to reverse actions through its undo/redo system.
