5.04-2. Bellman Ford Algorithm (1, part 2). Consider the scenario shown below, where at t=1, node e receives distance vectors from neighboring
nodes d, b, h and f. The (old) distance vector at e (the node at the center of the network) is also shown, before receiving the new distance vector from
its neighbors. Indicate which of the components of new distance vector at e below have a value of 2 after e has received the distance vectors from its
neighbors and updated its own distance vector. [Note: You can find more examples of problems similar to this here]
