Dijkstra Algorithm Questions
A vertex in a graph is a fundamental unit or element that represents a point or node. It is typically depicted as a circle or a point in a graph. Vertices are used to represent entities or objects, and they are connected by edges to form relationships or connections between them. In the context of the Dijkstra algorithm, vertices are used to represent the different nodes or locations in a graph, such as cities in a road network or nodes in a computer network.
