<｜begin▁of▁sentence｜>### Instruction:
Given a directed graph with the following edges (1, 2), (2, 3), (3, 4), (4, 2), what is the PageRank of each node if we use a damping factor (alpha) of 0.9?
### Response:
import networkx as nx

# Create a directed graph
digraph = nx.DiGraph()

# Add edges to the graph (nodes are added automatically)
digraph.add_edges_from([(1, 2), (2, 3), (3, 4), (4, 2)])

# Compute the PageRank of each node using a damping factor `alpha` of 0.9
pagerank_dict = nx.pagerank(digraph, alpha=0.9)

print(pagerank_dict)
