Elon Musk is running the graph construction business. A client has asked for a special graph. A graph
is called special if it satisfies the following properties:
●
●
It has <105 vertices.
It is a simple, undirected, connected 3-regular graph.
It has exactly k bridge edges, (k given as input).
For a graph G, define f(G) to be the minimum number of edges to be removed from it to make it
bipartite. The client doesn't like graphs with a high value of f, so you have to minimize it. If there
doesn't exist any special graph, print -1. Otherwise, find a special graph G with the minimum possible
value of f(G) and also find a subset of its edges of size f(G) whose removal makes it bipartite. In case
there are multiple such graphs, you can output any of those.Elon has assigned this task to you, now
you have to develop a C++ code that takes bridge edges as input and print all the possible graphs.
