What is the complexity of Dijkstra's algorithm?
Understand the Problem
The question is asking about the time complexity of Dijkstra's algorithm, which is used for finding the shortest path in a graph. The high-level approach requires understanding the algorithm's functionality and how it processes nodes and edges.
Answer
O(E log V) with min-priority queue and O(V^2) with adjacency matrix
The final answer is O(E log V) using a min-priority queue and O(V^2) using an adjacency matrix.
Answer for screen readers
The final answer is O(E log V) using a min-priority queue and O(V^2) using an adjacency matrix.
More Information
Dijkstra's algorithm is commonly used to find the shortest paths from a single source vertex to all other vertices in a weighted graph with non-negative weights.
