WebAug 18, 2024 · Discuss Given a graph and two nodes u and v, the task is to print the shortest path between u and v using the Floyd Warshall algorithm. Examples: Input: u = 1, v = 3 Output: 1 -> 2 -> 3 Explanation: Shortest path from 1 to 3 is through vertex 2 with total cost 3. The first edge is 1 -> 2 with cost 2 and the second edge is 2 -> 3 with cost 1. WebThe algorithm is named after the British mathematician Floyd Warshall. The algorithm is also known as the all-pairs shortest path algorithm. The algorithm compares all possible paths between two vertices in a graph and finds the shortest path. It does so in O (V 3) time even when the graph is sparse.
