void Dijkstra(T src) { unordered_map<T,int>dist; for(auto i:adjlist) { dist[i.fr]=INT_MAX; } set<pair<int,T>>s; dist[src]=0; s.insert(make_pair(dist[src],src)); while(!s.empty()) { auto p=*(s.begin()); T node=p.sc; int nodedist=p.fr; s.erase(s.begin()); for(auto childpair:adjlist[node]) { if(nodedist+childpair.sc<dist[childpair.fr]) { T dest=childpair.fr; auto f=s.find(make_pair(dist[dest],dest)); if(f!=s.end()) { s.erase(f); } dist[dest]=nodedist+childpair.sc; s.insert(make_pair(dist[dest],dest)); } } } }
Using Dijkstra algorithm, cheapest transportation cost can be calculated and while calculating cheapest transportation cost ,cheapest purchase price can also be calculated.

How can we assess whether a project is a success or a
failure?
This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects. Bombardier and Its Environment Joseph-Armand Bombardier was 15 years old when he built his first snowmobile...
