A shortest path tree from source node s in a graph G is a directed out-tree rooted from node s with the

A shortest path tree from source node s in a graph G is a directed out-tree rooted from node s with the property that the unique path (in the tree) from the node s to any node is a shortest path (in the graph G) to that node. Suppose that all directed cycles in a directed graph G have non-negative costs. Furthermore, suppose that the shortest path length II*(i) from node s to any other node i is known. Provide an algorithm to identify the shortest path tree for G. What is the running time for your algorithm?
