Dijkstra's algorithm is an algorithm for finding the shortest paths between nodes in a graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later. This programme is an implementation of https://en.wikipedia.org/wiki/Dijkstra%27s_algorithm#Pseudocode
