Question: In Dijkstra\'s algorithm, what data structure is commonly used to keep track of the minimum distance to each vertex?

Options:

Correct Answer: Priority Queue

Solution:

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

In Dijkstra's algorithm, what data structure is commonly used to keep track of the minimum distance to each vertex?

In Dijkstra's algorithm, what data structure is commonly used to keep track of the minimum distance to each vertex?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
Step 2: Recognize that each vertex (or point) in the graph has a distance value that represents how far it is from the starting point.
Step 3: To keep track of these distance values, we need a way to efficiently find the vertex with the smallest distance.
Step 4: A priority queue is a special data structure that allows us to quickly access the vertex with the smallest distance.
Step 5: When we update the distances of the vertices, the priority queue helps us manage these updates efficiently.

Dijkstra's Algorithm – An algorithm used 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 Dijkstra's algorithm.
