One of the most efficient algorithms to find the shortest distance in a graph is Dijkstra's algorithm. It works by maintaining a priority queue and visiting the closest unvisited node first, updating the distances from the source node as it goes. Here's how you can implement it in Swift:
main.swift854 chars24 lines
You can call this function with your graph, specifying the starting node:
main.swift270 chars10 lines
This will return an array of distances from the starting node to each node in the graph. For example, distances[4]
will give you the shortest distance from node 1 to node 4.
