What is the purpose of the 'visited' array in Dijkstra's algorithm?

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 process each vertex to find the shortest path.
Step 4: The 'visited' array is created to keep track of which vertices have already been processed.
Step 5: When a vertex is processed, it is marked in the 'visited' array.
Step 6: By using the 'visited' array, we can avoid processing the same vertex multiple times.
Step 7: This helps the algorithm run more efficiently and ensures we only consider each vertex once.
