WebMar 28, 2024 · Topological sort is a technique used in graph theory to order the vertices of a directed acyclic graph (DAG). It ensures that for every directed edge from vertex A to vertex B, vertex A comes before vertex B in the ordering. This is useful in scheduling problems, where tasks depend on the completion of other tasks. WebWhile there is a vertex in the graph do Display the vertex with 0 incoming edge (if many choose the one with lower lexical order) Remove it and its out-going links from the graph end The order is what the algo displays.

WebTopological Sort. Problems. Tutorial. Topological sorting of vertices of a Directed Acyclic Graph is an ordering of the vertices v 1, v 2,... v n in such a way, that if there is an edge directed towards vertex v j from vertex v i, … 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.
