如何解码多类型的嵌套数组？

def decode_nested_array(arr):
    result = []
    for item in arr:
        if isinstance(item, list):
            result.append(decode_nested_array(item))
        elif isinstance(item, dict):
            result.append(decode_nested_object(item))
        else:
            result.append(item)
    return result

def decode_nested_object(obj):
    result = {}
    for key, value in obj.items():
        if isinstance(value, list):
            result[key] = decode_nested_array(value)
        elif isinstance(value, dict):
            result[key] = decode_nested_object(value)
        else:
            result[key] = value
    return result
