中国道路交通网络信息查询系统【问题描述】出于不同的目的的旅客对交通工具有不同的要求。

例如，因公出差的旅客希望在旅途中的时间尽可能短，出门旅游的游客则期望旅费尽可能省，而老年旅客则要求中转次数最少。

编制一个全国城市间的交通咨询程序，为旅客提供两种或三种最优决策的交通咨询。

【系统要求】（1）提供对城市信息进行编辑（如：添加或删除）的功能。

（2）城市之间有两种交通工具：火车和飞机。

提供对列车时刻表和飞机航班进行编辑（增设或删除）的功能。

（3）提供两种最优决策：最快到达或最省钱到达。

全程只考虑一种交通工具；（4）旅途中耗费的总时间应该包括中转站的等候时间；（5）咨询以用户和计算机的对话方式进行。

由用户输入起始站、终点站、最优决策原则和交通工具，输出信息：最快需要多长时间才能到达或者最少需要多少旅费才能到达，并详细说明依次于何时乘坐哪一趟列车或哪一次班机到何地。
