Stack vs Queue vs Deque vs Priority Queue | DSA Comparison | 100 Days Programming | Day 35 in Hindi

Описание: 👉 Welcome to Day 34 of 100 Days Programming Way Challenges!

Today we cover Priority Queue in Python – one of the most powerful data structures for DSA and interviews.

✅ What is a Priority Queue?
A Priority Queue is a special type of queue where each element is assigned a priority.
Elements with higher priority are served before elements with lower priority.
Used in Operating Systems (CPU Scheduling), Graph Algorithms (Dijkstra), and Job Scheduling.*

✅ Types of Priority Queues:
Min Priority Queue → Smallest element served first
Max Priority Queue → Largest element served first

✅ Python Implementation:
Using heapq (Min Heap)
Using queue.PriorityQueue class
Custom comparator approach
