Question: In Dijkstra\'s algorithm, what data structure is commonly used to keep track of the nodes to be explored?

Options:

Correct Answer: Priority Queue

Solution:

A priority queue is used in Dijkstra\'s algorithm to efficiently retrieve the next node with the smallest tentative distance.

In Dijkstra's algorithm, what data structure is commonly used to keep track of the nodes to be explored?

In Dijkstra's algorithm, what data structure is commonly used to keep track of the nodes to be explored?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
Step 2: Recognize that the algorithm explores nodes based on their distances from the starting point.
Step 3: Identify that a data structure is needed to keep track of which nodes to explore next.
Step 4: Learn that a priority queue is the data structure used for this purpose.
Step 5: Understand that a priority queue allows the algorithm to efficiently get the node with the smallest distance.

Dijkstra's Algorithm – An algorithm for finding the shortest paths between nodes in a graph, particularly useful for weighted graphs.
Priority Queue – A data structure that allows for efficient retrieval of the minimum (or maximum) element, which is crucial for optimizing the performance of Dijkstra's algorithm.
