⚙️ How It Works

📝 Donor is added:

Inserted into Donor BST

Stored in HashMap with donation history, last donation, health flags

🧑‍⚕️ Patient Arrives:

Vital stats and blood type are input

Urgency level is calculated (services/urgency.py)

Stored in Priority Queue (patient_pq.py)

🧪 Blood Matching:

Check if matching blood exists in blood_inventory BST

If not, fetch eligible donor from Donor BST (sorted by donation time, proximity, and demand score)

If eligible, notify donor (console simulated)
