Code for student prerequisite subjects management system using trees?

Answer 1

To implement a student prerequisite subjects management system using trees, you can utilize a binary tree structure where each node represents a subject, and its children represent the prerequisite subjects. You can create classes for the Subject node and methods for adding subjects, checking prerequisites, and traversing the tree. For example, to add a subject, you would insert it into the tree based on its prerequisites, ensuring the hierarchy reflects the dependency relationships. Here's a simple Python structure to get started:

class Subject:
    def __init__(self, name):
        self.name = name
        self.prerequisites = []

    def add_prerequisite(self, subject):
        self.prerequisites.append(subject)

# Example usage
math = Subject("Math")
cs101 = Subject("CS101")
cs101.add_prerequisite(math)  # CS101 requires Math
