Which data structure can be used to represent a graph for Dijkstra's algorithm?
Step 1: Understand that a graph is made up of nodes (or vertices) and edges (connections between nodes).
Step 2: Know that Dijkstra's algorithm is used to find the shortest path between nodes in a graph.
Step 3: Learn that there are different ways to represent a graph in programming.
Step 4: One way to represent a graph is using an adjacency matrix, which is a 2D array where each cell indicates if there is an edge between two nodes.
Step 5: Another way is to use an adjacency list, which is a list where each node has a list of its connected nodes.
Step 6: You can also use arrays or linked lists to store the nodes and edges of the graph.
Step 7: Choose the data structure that best fits your needs based on the size of the graph and the operations you need to perform.
