A queue is a data structure that stores a collection of elements, with operations to enqueue (add) elements at the back of the queue, and dequeue (remove) elements from the front of the queue.
Stacks are based on the LIFO principle, i.e., the element inserted at the last, is the first element to come out of the list.29 mar. 2023
Whereas the stack only allows items to be added and removed to/from the top, any item in a heap can be accessed at any time.
This additional flexibility of the heap compared to the stack makes it a more complex data structure with higher overheads for managing the items that it holds.
A heap is like a tree structure where the top has the smallest or largest value.
A priority queue is like a waiting line where the highest-priority item is served first.
The two are often used together, with the heap helping to efficiently manage the priority queue.
Stack, heap, and queue are ways that elements are stored in memory.
Lets look at a queue first because that is similar to a line we would stand in at a bank to get a teller, or at a grocery store to check out.
With a queue, the first one in is the first one out.
