如何在多个数组中找到连续的数字？

def find_continuous_numbers(arrays):
    # 合并所有数组为一个列表
    all_numbers = [num for sublist in arrays for num in sublist]
    all_numbers.sort()  # 排序以便查找连续序列

    continuous_sequences = []
    current_sequence = [all_numbers[0]]

    for i in range(1, len(all_numbers)):
        if all_numbers[i] == all_numbers[i - 1] + 1:
            current_sequence.append(all_numbers[i])
        else:
            if len(current_sequence) > 1:  # 至少两个数字才算连续序列
                continuous_sequences.append(current_sequence)
            current_sequence = [all_numbers[i]]

    if len(current_sequence) > 1:
        continuous_sequences.append(current_sequence)

    return continuous_sequences

# 示例使用
arrays = [
    [1, 3, 5],
    [2, 4, 6],
    [10, 11, 12],
    [8, 9]
]

print(find_continuous_numbers(arrays))
