Question: 4. (6 points) Let G be a connected weighted graph with n vertices and which has nonnegative edge weights. Describe a modification of the Bellman-Ford

4. (6 points) Let G be a connected weighted graph with n vertices and which has nonnegative edge weights. Describe a modification of the Bellman-Ford algorithm which identifies all single-source shortest paths of length k (for some fixed k < n) but which has a lower runtime than the standard Bellman-Ford algorithm.
