Transcribed Image Text:
You are given a directed acyclic graph G = (V, E) with unweighted edges. Every vertex v € V has an integer score s[v]. For a vertex v, we say that a vertex u is an ideal target for v if: 1. It is possible to go from v to u. 2. s[u] is maximized. In other words, out of all vertices that u can reach, u (i.e. v's ideal target) is the one with the maximum score. Given the scores for all vertices, describe a linear-time algorithm to find the ideal targets for every vertex v. (Note that v can be its own ideal target.) Just provide the algorithm description and runtime analysis. Proof of correctness and space complexity analysis are not required.
