<｜begin▁of▁sentence｜>### Instruction:
Given the American College football network graph which you can read from a gml file named `football.gml`, can you use the `kcut` function in `cdlib` to perform community detection and provide the resulting community structure in JSON format? Hint: Use `kmax=4` as a parameter for the KCut algorithm.
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph
G = nx.read_gml('football.gml')

# Perform community detection using KCut
coms = algorithms.kcut(G, kmax=4)

# Convert the community structure to JSON
coms_json = coms.to_json()

print(coms_json)
