<｜begin▁of▁sentence｜>### Instruction:
Given a directed graph with the edge set [(1, 2), (1, 3), (3, 4), (2, 5)], how to compute the group out-degree centrality for the group of nodes [1, 2] using NetworkX?
### Response:
import networkx as nx

# Create a directed graph
G = nx.DiGraph()
G.add_edges_from([(1, 2), (1, 3), (3, 4), (2, 5)])

# Define a group of nodes
S = [1, 2]

# Compute the group out-degree centrality
centrality = nx.algorithms.centrality.group_out_degree_centrality(G, S)

print("Group out-degree centrality:", centrality)
