    题目描述
    Every day, N passengers arrive at Takahashi Airport. The i-th passenger arrives at time Ti.

    Every passenger arrived at Takahashi airport travels to the city by bus. Each bus can accommodate up to C passengers. Naturally, a passenger cannot take a bus that departs earlier than the airplane arrives at the airport. Also, a passenger will get angry if he/she is still unable to take a bus K units of time after the arrival of the airplane. For that reason, it is necessary to arrange buses so that the i-th passenger can take a bus departing at time between Ti and Ti+K (inclusive).

    When setting the departure times for buses under this condition, find the minimum required number of buses. Here, the departure time for each bus does not need to be an integer, and there may be multiple buses that depart at the same time.

    Constraints
    2≤N≤100000
    1≤C≤109
    1≤K≤109
    1≤Ti≤109
    C, K and Ti are integers.

    输入
    The input is given from Standard Input in the following format:

    N C K
    T1
    T2
    :
    TN

    输出
    Print the minimum required number of buses.

    样例输入
    复制样例数据
    5 3 5
    1
    2
    3
    6
    12
    样例输出
    3

    提示
    For example, the following three buses are enough:
    A bus departing at time 4.5, that carries the passengers arriving at time 2 and 3.
    A bus departing at time 6, that carries the passengers arriving at time 1 and 6.
    A bus departing at time 12, that carries the passenger arriving at time 12.

    思路:就是一个贪心或者说是模拟,要么车满,要么时间到了。

    #include <iostream>
    #include <cstdio>
    #include <algorithm>
    #include <vector>
    using namespace std;
    const int N=100000+5;
    int t[N];
    int n,k,c;
    int main()
    {
    	int p=1,cnt=1,ti;
    	scanf("%d%d%d",&n,&c,&k);
    	for(int i=1;i<=n;i++)
    		scanf("%d",&t[i]);
    	sort(t+1,t+n+1);
    	ti=t[1]+k;
    	for(int i=2;i<=n;i++)
    	{
    		if(t[i]>ti||p==c)//时间过了或者车满了
    		{
    			cnt++;
    			ti=t[i]+k;
    			p=1;
    		}
    		else
    			p++;
    	}
    	printf("%d",cnt);
    }

    Bayan Bus

    The final round of Bayan Programming Contest will be held in Tehran, and the participants will be carried around with a yellow bus. The bus has 34 passenger seats: 4 seats in the last row and 3 seats in remaining rows.
    在这里插入图片描述

    The event coordinator has a list of k participants who should be picked up at the airport. When a participant gets on the bus, he will sit in the last row with an empty seat. If there is more than one empty seat in that row, he will take the leftmost one.
    In order to keep track of the people who are on the bus, the event coordinator needs a figure showing which seats are going to be taken by k participants. Your task is to draw the figure representing occupied seats.

    input
    The only line of input contains integer k, (0 ≤ k ≤ 34), denoting the number of participants.
    output
    Print the figure of a bus with k passengers as described in sample tests. Character ‘#’ denotes an empty seat, while ‘O’ denotes a taken seat. ‘D’ is the bus driver and other characters in the output are for the purpose of beautifying the figure. Strictly follow the sample test cases output format. Print exactly six lines. Do not output extra space or other characters.
    Examples
    Input
    9
    output
    ±-----------------------+
    |O.O.O.#.#.#.#.#.#.#.#.|D|)
    |O.O.O.#.#.#.#.#.#.#.#.|.|
    |O…|
    |O.O.#.#.#.#.#.#.#.#.#.|.|)
    ±-----------------------+
    input
    20
    output
    ±-----------------------+
    |O.O.O.O.O.O.O.#.#.#.#.|D|)
    |O.O.O.O.O.O.#.#.#.#.#.|.|
    |O…|
    |O.O.O.O.O.O.#.#.#.#.#.|.|)
    ±-----------------------+
    题意:题意很简单,输入一个数,这个数代表上车人数,每次上车都从左边靠窗坐,直至坐满。
    方法:看到这道题的输出有很多固定的字符,首先想到可以用strcpy数组来存好,然后看上了几个人就改变九个位置。

    #include"cstdio"
    #include"cstring"
    #include"iostream"
    #include"algorithm"
    using namespace std;
    int main()
    {
     int n;
     while(cin>>n)
     {
      char a[7][28];
      strcpy(a[0],"+------------------------+");
      strcpy(a[1],"|#.#.#.#.#.#.#.#.#.#.#.|D|)");
      strcpy(a[2],"|#.#.#.#.#.#.#.#.#.#.#.|.|");
      strcpy(a[3],"|#.......................|");
      strcpy(a[4],"|#.#.#.#.#.#.#.#.#.#.#.|.|)");
      strcpy(a[5],"+------------------------+");
      for(int i=0;i<=22;i++)
      {
       for(int j=0;j<6;j++)
       {
        if(a[j][i]=='#')
        {
         a[j][i]='0';
         n--;
         if(!n)
         {
          break;
         }
        }
       }
       if(!n)
       {
        break;
       }
      }
      for(int i=0;i<6;i++)
      {

    2013-02-04 下面学习一些airport 的英语:

    1Firstly, let us study some worlds:

    Passengers:
    (a person in a car or on a bus, train, or plane)

    departure:
    (The act of leaving a place)
    example:
    The list of departure tells you when the flights are leaving.

    flight attendant:
    (a person who helps passengers on a plane)
    example:
    Ask the flight attendant to get you a blanket.

    gate:
    (the plce in an airport where you leave the building and enter the plane)
    example:
    We need to find out which gate our flight leaves from, let's check the screen.

    documents:
    (an offical paper)
    example:
    I have all my travel documents; my tickets; passport,and visa.

    immigration:
    (the system of deciding who can enter a country, OR the place where someone checks the passports and other papers of people coming into the country)
    example:
    In some countries, you can get your visa at immigration as you enter the conutry.

    baggage claim:
    (the place where you get your luggage)
    example:
    I'll go to baggage claim to get my suitcase, then I will meet you outside.

    at customs:
    (the system of controlling items people bring into a foreign conutry, or the place where luggage is checked when you enter a foreign country.)

    下面来练习一下:
    1:Our arrival in HongKong was right on time.
    2: Please listen to the safety instructions given by the flight attendant.
    3: Before we get on plane, we have to wait at the gate.
    4: This flight is full, there are many passengers on the plane.
    5: Please take your seats so we can have on-time departure to Los-angeles
    6: Here are all of the documents for yor visa.
    7: Before he went to customes, Andy got his bags at baggage claim.
    8: You must show your passport at immigration when you enter a new country.
    9: I don't see our flight on the schedule display anymore. I hope it is not cancelled.
    10: Do not bring your computer on vaction. The purpose of this trip is to relax, not to work.
    11: Airline worker: Do you want a one-way ticket to Bombay?
        Customer: No I'd like a round-trip ticket, please. I want to come back next wek.
    12: When you enter a country, you have to tell what thing you are bring with you, you can declare things at customs.
