<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (0, 2), (1, 2), (2, 3), (3, 1), (3, 0)], can you calculate the minimum cut and represent this cut as a string using the __str__ method in igraph?
### Response:
import igraph as ig

# create a graph
g = ig.Graph([(0, 1), (0, 2), (1, 2), (2, 3), (3, 1), (3, 0)])

# perform a minimum cut
cut = g.mincut()

# use the overridden __str__ method to get a string representation of the cut
str_cut = cut.__str__()

print(str_cut)
