Need help with this algorithm problem

Problem 3: Given a directed acyclic graph G (V, E) you want to find the length L of the longest path in the graph. . Use DFS to get a topological sort of the nodes vi..., un Denote with Li] the length of the longest path starting at v. Express L(G) as a function of Lj] for j> i. Use dynamic program ming to fill the array L[i],, .. ,L[n] and use these values to compute L . . . What is the running time of your algorithm as a function of n = |v| and m-E
