In Dijkstra's algorithm, what does the priority queue store?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
Step 2: Know that a graph consists of vertices (points) and edges (connections between points).
Step 3: Realize that during the algorithm, we need to keep track of which vertices we have visited and which we have not.
Step 4: The priority queue is a special data structure that helps us manage the unvisited vertices.
Step 5: The priority queue stores only the unvisited vertices that we still need to explore.
Step 6: Each vertex in the priority queue has a tentative distance, which is the current shortest distance we know to reach that vertex.
Step 7: The priority queue allows us to efficiently select the vertex with the smallest tentative distance to visit next.
