Problem 6. Dijkstra's algorithm does not generally work for graphs with negative weights. It might seem like this could be addressed simply by determining the lowest weight of any edge in the given graph, adding that weight to all edges' weights, then running Dijkstra's algorithm, and finally subtracting weights again to adjust the weights of the computed shortest paths. But this, in fact, does not work. Give an example of a graph G for which this modified version of Dijkstra's algorithm computes at least one incorrect shortest path and point out a pair of vertices along with the incorrectly computed path and a correct path
