A priority queue is a data structure that stores elements with associated priorities. It allows efficient insertion and removal of elements based on their priority values. One way to implement a priority queue is by using a linked list.<\/p>\n
In a linked list-based implementation of a priority queue, each element is represented by a node that contains the actual data and a priority value. The nodes are linked together to form a linked list structure.<\/p>\n
A priority queue using linked list offers flexibility in terms of efficient insertion and deletion operations. However, it may require linear time complexity for operations like insertion and deletion since finding the appropriate position or the element with the highest priority may involve traversing the linked list.<\/p>\n
Priority queue is an abstract data type, It is a type of queue in which each element has a priority assigned to it. The priority of the element determines the order in which elements are removed from the priority queue. In the priority queue, all the elements are arranged either in ascending order or descending order.<\/p>\n

Linked list is a linear data structure just like arrays. In the linked list the elements are not stored in contiguous locations, the elements are connected or linked using pointers. Each node stores the data and the address of the next node.<\/p>\n

The highest priority element will always be the head of the linked list. The list will be arranged in the descending order based on the priority of the elements due to which we can remove the highest priority element in O(1) time.
\nFor inserting an element we have to traverse the list and find the proper position to insert the element so that the sequence of the priority queue will be maintained.<\/p>\n
