What data structure is typically used to implement Dijkstra's algorithm efficiently?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph.
Step 2: Recognize that the algorithm needs to keep track of nodes and their distances from the starting point.
Step 3: Realize that we need a way to quickly find the node with the smallest distance to explore next.
Step 4: Learn that a priority queue is a special data structure that allows us to efficiently get the node with the smallest distance.
Step 5: Conclude that using a priority queue helps Dijkstra's algorithm run faster by minimizing the time it takes to find the next node.

Dijkstra's Algorithm – An algorithm for finding the shortest paths between nodes in a graph.
Priority Queue – A data structure that allows for efficient retrieval of the highest (or lowest) priority element.
