i (6 marks) Consider a weighted version of the directed graph in (a.), given below. Carry out the steps of Dijkstra's shortest path algorithm starting at vertex S, and consequently dive the shortest poth from S to vertex T and its lengrth ii (2 marks) For a graph G (V, E), what is the worst-case time complexity of the version of Dijkstra's shortest path algorithm examined in lectures? (Your answer should be in terms of V and/or E.)
