WebJul 1, 2024 · Method 1 : The graph must follow these properties: If there are n vertices then there must be n-1 edges. It should be connected i.e. every vertex can be reached with atleast one other vertex. In trees, every node/vertex is connected to atleast one other vertex. Also the total number of edges is also n-1 for n nodes.

WebDefinitions Tree. A tree is an undirected graph G that satisfies any of the following equivalent conditions: . G is connected and acyclic (contains no cycles).; G is acyclic, and a simple cycle is formed if any edge is added to G.; G is connected, but would become disconnected if any single edge is removed from G.; G is connected and the 3-vertex … WebIf the graph is a complete graph, then the spanning tree can be constructed by removing maximum (e-n+1) edges, where 'e' is the number of edges and 'n' is the number of vertices. So, a spanning tree is a subset of connected graph G, and there is no spanning tree of a disconnected graph. Minimum Spanning tree.
