Priority Queue
A priority queue is a data structure that stores elements in order of their priority. Elements with higher priorities appear higher in the queue, with elements with lower priorities appearing lower.
Example:
Priority Queue {
3,
1,
5,
2
}
Priority Queue {
Tom,
Alice,
John,
Sarah
}
Priority Queue {}
Key Features:
Elements can have multiple priorities.
The element with the highest priority is served first.
Elements with lower priorities are served later.
The queue is maintained in the order of increasing priority.
The operations add, remove, and peek at the top element in the queue are all efficient.
Applications:
Job scheduling: Used to schedule tasks based on their priority.
Scheduling and resource allocation: Managing tasks that require attention.
Call centers: Handling multiple calls with different priorities.
Cache systems: Keeping frequently accessed data in memory.
Shortest path algorithms: Finding the shortest path between two points
