What is the best time complexity we can achieve to precompute all-pairs shortest paths in a weighted graph?
Question
Solution 1
The best time complexity we can achieve to precompute all-pairs shortest paths in a weighted graph is O(V^3), where V is the number of vertices in the graph. This can be achieved using Floyd-Warshall algorithm.
Here are the steps:
- Initialize a 2D array, dist[][], such that dist[i][j] holds the Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
