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

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

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path from a starting point (source vertex) to other points in a graph.
Step 2: Realize that as the algorithm runs, it needs to keep track of the shortest distance to each vertex from the source.
Step 3: Know that a priority queue is a special data structure that allows us to efficiently get the vertex with the smallest distance.
Step 4: When the algorithm needs to explore the next vertex, it uses the priority queue to quickly find the one with the smallest distance.
Step 5: This helps the algorithm work faster and more efficiently, as it doesn't have to look through all vertices each time.
