Given a directed graph whose underlying undirected graph is a tree, compute for every node the minimum number of edge reversals required so that starting from that node you can reach all other nodes. This reduces to a tree shortest-path / rerooting problem by treating each original edge as cost 0 in its given direction and cost 1 if reversed, solvable with a 0-1 BFS or tree DP + rerooting to obtain answers for all nodes.
