"The usual algorithms for topological sorting have running time linear in the number of nodes plus the number of edges, asymptotically, One of these algorithms, first described by Kahn (1962), works by choosing vertices in the same order as the eventual topological sort. First, find a list of "start nodes" which have no incoming edges and insert them into a set S; at least one such node must exist in a non-empty acyclic gr… " - Graph topological order

WebIn your case sorted means : the second one does not depend of the first one. [3 4 1 2] and [4, 3, 2, 1] are two possible orders. The algorithm suppose transitivity : if x <= y and y <= z then x <= z. In this case it's not true. You can however modify the data : if x depends of y and y depends of z then add z to x' dependency list.
