如何找到二维数组中的常见数字或异常，并使其触发其他内容

def find_common_or_exception(arr):
    count_dict = {}
    common_num = None
    exception_num = None

    # 遍历二维数组，统计数字出现次数
    for row in arr:
        for num in row:
            if num in count_dict:
                count_dict[num] += 1
            else:
                count_dict[num] = 1

    # 找到常见数字和异常
    for num, count in count_dict.items():
        if common_num is None or count > count_dict[common_num]:
            common_num = num
        if exception_num is None or count < count_dict[exception_num]:
            exception_num = num

    # 触发其他内容
    if common_num is not None:
        print("常见数字是:", common_num)
        # 触发其他操作或逻辑
    if exception_num is not None:
        print("异常数字是:", exception_num)
        # 触发其他操作或逻辑

# 示例二维数组
array = [[1, 2, 3], [2, 3, 4], [3, 4, 5], [4, 5, 6], [5, 6, 7], [6, 7, 8], [7, 8, 9], [8, 9, 10], [9, 10, 11], [10, 11, 12]]
