body: <p>How to apply dijkstra algorithm on this graph?
  I've been trying, but I cant figure out hows it going?</p>
  
  <p>For example if we are to find shortest path from a to c, then shouldn't it be 3 as the shortest one go from a to b (1) and then b to c (2), so total 3 weight. However, answer is showing 4 that is direct from a to c.</p>
  
  <p>Any help here?</p>
