Which data structure is commonly used to implement Dijkstra's algorithm?
Steps
Concepts
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.
Step 3: Learn that a priority queue is a special data structure that allows us to efficiently get the node with the smallest distance.
Step 4: Realize that the priority queue helps Dijkstra's algorithm work faster by always accessing the closest node next.
