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. WebAlso, you will find working examples of adjacency list in C, C++, Java and Python. An adjacency list represents a graph as an array of linked lists. The index of the array represents a vertex and each element in its linked …
