Learn Djistra or Maximum Spanning Tree(krustal algorithm). These algorithms uses priority queue,because we want the 'less' distance and we need a queue that it is sorted by distance.

    I think you mean "minimum spanning tree"?? and Kruskal algorithm doesn't uses priority queue ..

      That depends on implementation. It's certainly not necessary, since you can just sort the edges and process them in order, but you can use a priority queue if you want.
