WebThe first line contains the number of nodes n (2 ≤ n ≤ 10 5).. The next n - 1 lines contain four integers each, denoting the i-th thread of the cobweb: the nodes it connects u i, v i (1 ≤ u i ≤ n, 1 ≤ v i ≤ n), the clamminess of the thread x i (1 ≤ x ≤ 10 9 + 6), and the color of the thread c i ().The red color is denoted by 0, and the black color is denoted by 1. WebJul 17, 2024 · Spanning Tree. A spanning tree is a connected graph using all vertices in which there are no circuits. In other words, there is a path from any vertex to any other vertex, but no circuits. Some examples of spanning trees are shown below. Notice there are no circuits in the trees, and it is fine to have vertices with degree higher than two.

WebNov 26, 2024 · Approach: The given problem can be solved using Kruskal’s algorithm to find the Minimum Spanning tree. We find the vertex which has maximum degree in the graph. At first we will perform the union of all the edges which are incident to this vertex and then carry out normal Kruskal’s algorithm. This gives us optimal spanning tree.
