<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (1, 2), (2, 3), (3, 0)], can you create a vertex cover from the minimum cut and produce a string representation of this vertex cover?
### Response:
from igraph import Graph, VertexCover

# Create a sample graph
g = Graph(edges=[(0, 1), (1, 2), (2, 3), (3, 0)])

# Find a vertex cover for the graph
vertex_cover = g.mincut().add_cut_vertices()

# Create a VertexCover object
vc_obj = VertexCover(g, vertex_cover)

# Get a string representation of the vertex cover
print(str(vc_obj))
