如何找到两个图的数值交集

def find_intersection(graph1, graph2):
    intersection = []
    for i in range(len(graph1)):
        for j in range(len(graph1[i])):
            if graph1[i][j] == 1 and graph2[i][j] == 1:
                intersection.append(i)
                break
    return intersection

# 示例图的邻接矩阵表示
graph1 = [
    [0, 1, 0, 1],
    [1, 0, 1, 0],
    [0, 1, 0, 1],
    [1, 0, 1, 0]
]

graph2 = [
    [0, 1, 0, 0],
    [1, 0, 1, 0],
    [0, 1, 0, 1],
    [0, 0, 1, 0]
]

intersection = find_intersection(graph1, graph2)
print(intersection)
