<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (0, 2), (1, 2), (1, 3), (3, 4)], how can you use VertexCover.VertexCover.__len__ from igraph to determine the number of clusters in the vertex cover?
### Response:
from igraph import Graph, VertexCover

# Define the edges of the graph
g = Graph(edges=[(0, 1), (0, 2), (1, 2), (1, 3), (3, 4)])

# Compute a vertex cover
vc = g.mincut().as_cover()

# Get the number of clusters in the vertex cover
num_clusters = len(vc)

print('Number of clusters in the vertex cover:', num_clusters)
