WebFeb 6, 2024 · Given a Directed Acyclic Graph having V vertices and E edges, where each edge {U, V} represents the Jobs U and V such that Job V can only be started only after completion of Job U.The task is to determine the minimum time taken by each job to be completed where each Job takes unit time to get completed. Examples: WebTopological ordering. A topological ordering of the vertices of a directed acyclic graph is a sequence of its vertices in which each vertex appears exactly once. For every pair of distinct vertices v and w in the sequence, if the edge v → w exists, then v appears earlier in the sequence than w..
