Check whether an undirected graph contains cycle or not

WebA minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. That is, it is a spanning tree whose sum of edge weights is as small as possible. More generally, any … WebIf our graph is connected and doesn’t contain a cycle then it will be a tree.
