Dijkstra	O(ElogE) with heap. O(E + VlogV) with Fabonacci Heap	Single Source to All	Heap with closest nodes
Floyd-Warshall	O(V^3)	All to All	Use each node as a intermediate node to update `N^2` pairs of nodes

Bellman-Ford

O(VE)

Single Source to All

Use all the edges to relax V-1 times

Dijkstra

O(ElogE) with heap. O(E + VlogV) with Fabonacci Heap

Single Source to All

Heap with closest nodes

Floyd-Warshall

O(V^3)

All to All

Use each node as a intermediate node to update N^2 pairs of nodes
