WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebThe process of constructing a compatible total order for a given partial order is called topological sorting. It is known that every finite partially ordered set (A, ≼) can be represented by a directed graph G. The vertices of G correspond to the elements of set A, and the edge from a to b exists if and only if a ≼ b.

WebIt is because if a graph G has a directed cycle that means it would have a back-edge, which means when trying to form a topological ordering from at least one of the edges we will have a edge back to one of the earlier edges, or even to the starting edge, in some cases, depending on the graph.It has been seen that having a directed cycle is the ... WebThere can be multiple approaches to find the topological sort of a graph. We will discuss one such simple approach here- 1️⃣Calculate the in-degree of every vertex. 2️⃣Start from the vertex having an in-degree of 0. 3️⃣Write that vertex in the answer. 4️⃣Remove that vertex and all the outgoing edges from it.
