<｜begin▁of▁sentence｜>### Instruction:
Consider you have a graph where nodes 1 to 4 form a clique (every node is connected to every other node), and node 5 is connected only to node 4. If you need to find the subgraph of nodes that are part of the 2-core but have exactly two neighbors within the 2-core, how would you use NetworkX's 'k_corona' function to obtain this?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()

# Add nodes to the graph
G.add_nodes_from([1, 2, 3, 4, 5])

# Add edges to the graph
G.add_edges_from([(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4), (4, 5)])

# Compute the core number for each node
core_numbers = nx.core_number(G)

# Find the 2-corona of the graph
k_corona_subgraph = nx.k_corona(G, k=2, core_number=core_numbers)

# Print the nodes of the 2-corona subgraph
print('Nodes in 2-corona:', k_corona_subgraph.nodes())
# Print the edges of the 2-corona subgraph
print('Edges in 2-corona:', k_corona_subgraph.edges())
