Question: In Dijkstra\'s algorithm, what data structure is typically used to keep track of the shortest path estimates?

Options:

Array
Linked List
Stack
Priority Queue

Correct Answer: Priority Queue

Solution:

A priority queue is used to keep track of the shortest path estimates in Dijkstra\'s algorithm, allowing efficient retrieval of the next vertex with the smallest distance.

In Dijkstra's algorithm, what data structure is typically used to keep track of the shortest path estimates?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
Step 2: Recognize that we need a way to keep track of the distances from the starting point to each vertex.
Step 3: Learn that a priority queue is a special data structure that allows us to efficiently get the vertex with the smallest distance.
Step 4: Realize that the priority queue helps us update and retrieve the shortest path estimates as we explore the graph.

Dijkstra's Algorithm – An algorithm used for finding the shortest paths between nodes in a graph.
