实现一个简单的电信计费程序，针对手机的短信采用如下计费方式：
1、接收短信免费，发送短信0.1元/条，超过3条0.2元/条，超过5条0.3元/条。
2、如果一次发送短信的字符数量超过10个，按每10个字符一条短信进行计算。

输入：
输入信息包括两种类型
1、逐行输入南昌市手机用户开户的信息，每行一个用户。
格式：u-号码计费类型（计费类型包括：0-座机 1-手机实时计费 2-手机A套餐 3-手机短信计费）
例如：u-13305862264 3
座机号码由区号和电话号码拼接而成，电话号码包含7-8位数字，区号最高位是0。
手机号码由11位数字构成，最高位是1。
本题只针对类型3-手机短信计费。
2、逐行输入本月某些用户的短信信息，短信的格式：
m-主叫号码，接收号码，短信内容（短信内容只能由数字、字母、空格、英文逗号、英文句号组成）
m-18907910010 13305862264 welcome to jiangxi.
m-13305862264 18907910010 thank you.

注意：以上两类信息，先输入所有开户信息，再输入所有通讯信息，最后一行以“end”结束。
输出：
根据输入的详细短信信息，计算所有已开户的用户的当月短信费用（精确到小数点后2位，单位元）。假设每个用户初始余额是100元。
每条短信信息均单独计费后累加，不是将所有信息累计后统一计费。
格式：号码+英文空格符+总的话费+英文空格符+余额
每个用户一行，用户之间按号码字符从小到大排序。
错误处理：
输入数据中出现的不符合格式要求的行一律忽略。
本题只做格式的错误判断，无需做内容上不合理的判断，比如同一个电话两条通讯记录的时间有重合、开户号码非南昌市的号码、自己给自己打电话等，此类情况都当成正确的输入计算。但时间的输入必须符合要求，比如不能输入2022.13.61 28:72:65。

本题只考虑短信计费，不考虑通信费用以及月租费。

建议类图：
参见图1、2、3：

图1

图1中User是用户类，包括属性：
userRecords （用户记录）、balance（余额）、chargeMode（计费方式）、number（号码）。
ChargeMode是计费方式的抽象类：
chargeRules是计费方式所包含的各种计费规则的集合，ChargeRule类的定义见图3。
getMonthlyRent（）方法用于返回月租（monthlyRent）。
UserRecords是用户记录类，保存用户各种通话、短信的记录，
各种计费规则将使用其中的部分或者全部记录。
其属性从上到下依次是：
市内拨打电话、省内（不含市内）拨打电话、省外拨打电话、
市内接听电话、省内（不含市内）接听电话、省外接听电话的记录
以及发送短信、接收短信的记录。

图2

    图2中CommunicationRecord是抽象的通讯记录类：
包含callingNumber拨打号码、answerNumber接听号码两个属性。
CallRecord（通话记录）、MessageRecord（短信记录）是它的子类。

图3
图3是计费规则的相关类，这些类的核心方法是：
calCost（ArrayList callRecords）。
该方法针根据输入参数callRecords中的所有记录计算某用户的某一项费用；如市话费。
输入参数callRecords的约束条件：必须是某一个用户的符合计费规则要求的所有记录。
SendMessageRule是发送短信的计费规则类，用于计算发送短信的费用。
LandPhoneInCityRule、LandPhoneInProvinceRule、LandPhoneInLandRule三个类分别是座机拨打市内、省内、省外电话的计费规则类，用于实现这三种情况的费用计算。

（提示：可以从UserRecords类中获取各种类型的callRecords）。

注意：以上图中所定义的类不是限定要求，根据实际需要自行补充或修改。

}

我滴总结：

前面的框架已经搭好，现在只需要在原有基础上增添短信了

没什么好嗦的。

新增短信计费，短信类重写了

短信类容截取输入内容28位后面的就行，

短信计费是分段计费，要注意一下。
