题目描述
魔术师将一叠扑克顺次在桌上排成一行，初始全部正面朝上。随后，他每次挥一挥衣袖，都会翻转一连串的扑克，改变它们的正反朝向。从古代传下来的规矩，魔术师皆有师傅，他们要随时准备回答师傅的问题。问题形如：目前从第i张扑克牌到第j张扑克牌中，有几张正面朝上？
作为魔术师的助手，你被要求学习程序设计、算法与数据结构。现在，魔术师把这个问题交给了你，你需要编写一个程序，维护相应的数据结构来保存桌子上牌面的情况，同时对于师傅的每一个问题，你要用尽量快的速度计算出答案。
输入
第一行包含三个正整数n、p和q。n表示扑克牌的数量，p表示魔术师的挥一挥次数，q表示师傅的问话次数。
接下来共p+q行，每行包含一个操作，操作分为2种：
H i j 魔术师挥一挥，改变了第i张牌到第j张牌的正反
Q i j 师傅问话：截至目前，第i张到第j张牌中有多少张正面朝上
操作中恰好包含p次H操作，q次Q操作，与第一行的p和q吻合。H操作和Q操作的范围均包含边界（即第i张和第j张牌）。
对于每个操作，输入保证1 ≤ i ≤ j ≤ n。
输出
对于每次Q操作，输出一行，包含一个整数，表示问题的答案。
提示：线段树(Pokeface
Title Description
The magician will stack poker table sequentially in a row, all the initial face-up. He then every wisp will flip a series of poker pros and cons of changing their orientation. The rules handed down ancient times, the master magician Jie, they be ready to answer the teacher s questions. Question of the form: Currently playing cards i to j-card poker, there are a few face-up?
As a magician s assistant, you are required to learn programming, algorithms and data structures. Now, the magician put this question to you, you need to write a program to maintain appropriate data structure to hold the cards on the table face the situation, while the master for each question, and you want to use as quickly calculate the answer.
Enter
The first line contains three positive integers n, p and q. n represents the number of poker, p represents the wave of the magic number, q represents the number of master s questioning.
Next, a total of p+ q rows, each containi)

容积卡尔曼滤波测量方程基于统计数据，利用蒙特卡罗方法抽取私家电动汽车一次出行里程数，根据电池充电特性及车辆行驶习惯获得电动汽车充电的起始荷电状态、充电功率和起始充电时间，建立了一个较为精确的预测无线充电私家电动汽车充电负荷的数学模型，(The volume Calman filter measurement equation is based on the statistical data, using Monte Carlo method to extract the first trip mileage of private electric vehicles. Based on the battery charging characteristics and vehicle driving habits, the initial charge state, charging power and starting charge time of the electric vehicle charging are obtained. A more accurate prediction radio is established. A mathematical model of charging load for private electric vehicles.)

VB编写实现的简历打印程序，一眼看上去还挺不错嘛。将程序简历设计成表格的样式，这也是大家习惯用的格式，有放照片的地方，还有个人信息的填写，另外还可打印，简历信息可保存至Access数据库，稍加修改就可制作成一款简历管理软件。选中每一个简历，就可方便的打印出来(VB prepared to achieve resume printing process, one looks pretty bad. The program is designed to form a style resume, which is the format we used to use, there is a place to put photos, and fill in personal information, while also printing, resume information can be saved to an Access database, a little change can be made into a shall resume management software. Each resume is selected, you can easily print out)
