资源摘要信息: "distance_to_school" 标题:“distance_to_school”表明这个文件或项目是与计算到学校的距离相关的内容。由于标题没有提供更具体的信息,我们可以推断这个项目可能涉及到地理信息系统(GIS)或者简单的地理计算。这可能是一个Python脚本、一个程序库或者一个完整的应用程序,旨在帮助用户计算从一个点(可能是用户的家或者其他任何地点)到学校的具体距离。 描述:“distance_to_school”作为描述与标题完全相同,没有提供额外的信息。基于标题,我们可以合理推测描述可能指的是一个用于测量或计算到学校距离的工具或程序。这种工具可能使用GPS坐标、街道地址或其他地理参照点来确定起点和终点之间的距离,并可能提供行驶距离和步行距离两种计算方式。 标签:“Python”这个标签表明文件与Python编程语言有关。Python是一种广泛使用的高级编程语言,它以简洁明了的语法著称,特别适合快速开发应用程序和数据处理。使用Python标签表明这个“distance_to_school”项目可能是用Python语言编写的,这意味着它可能使用了Python的某些库,如geopy、folium或者shapely等来处理与地理位置相关的信息。 压缩包子文件的文件名称列表:“distance_to_school-master”这一项表明我们正在处理的是一个压缩的文件包,文件包的主分支名称是“master”。通常在Git版本控制系统中,“master”分支是默认的主分支,代表项目的主版本。由于文件名中没有包含任何文件扩展名(如.zip或.tar.gz),我们可以推断这是一个Git仓库,可能托管在GitHub或类似的代码托管平台上。 鉴于以上信息,我们可以推断出“distance_to_school”项目可能是一个基于Python开发的程序,它能够帮助用户计算从当前所在位置到学校的位置的最短距离。项目可能涉及到以下知识点: 1. Python编程语言:项目的开发语言,用来编写算法和逻辑。 2. 地理信息系统(GIS):用于处理地理数据,计算距离和路径。 3. GPS坐标和地理参照系统:用于精确地定位地点。 4. geopy库:一个Python客户端,可以用来进行地理编码和反地理编码,计算两个GPS坐标之间的距离。 5. folium库:一个Python库,用于在网页上显示和操作地图。 6. shapely库:一个用于处理和分析平面几何对象的Python库。 7. 网络爬虫技术(如果项目涉及到在线获取地址信息):可能需要提取网页上的地址信息。 8. 数据可视化:如果项目需要在地图上展示距离或路径,可能会涉及到数据可视化技术。 项目可能包括以下功能: - 允许用户输入地址或坐标,并从数据库中获取相应的GPS坐标。 - 使用这些坐标来计算直线距离(欧几里得距离)或实际行驶距离。 - 在地图上标注起点和终点,并提供可能的路线选项。 - 如果是一个交互式应用,可能包含用户界面,使用户能够轻松地输入信息并查看结果。 结合Python与GIS相关知识,该项目可能用于教育、城市规划、导航或个人日常使用,特别是在需要规划最佳路线以节省时间和资源的场景中。

用代码解决这个问题The program committee of the school programming contests, which are often held at the Ural State University, is a big, joyful, and united team. In fact, they are so united that the time spent together at the university is not enough for them, so they often visit each other at their homes. In addition, they are quite athletic and like walking. Once the guardian of the traditions of the sports programming at the Ural State University decided that the members of the program committee spent too much time walking from home to home. They could have spent that time inventing and preparing new problems instead. To prove that, he wanted to calculate the average distance that the members of the program committee walked when they visited each other. The guardian took a map of Yekaterinburg, marked the houses of all the members of the program committee there, and wrote down their coordinates. However, there were so many coordinates that he wasn't able to solve that problem and asked for your help. The city of Yekaterinburg is a rectangle with the sides parallel to the coordinate axes. All the streets stretch from east to west or from north to south through the whole city, from one end to the other. The house of each member of the program committee is located strictly at the intersection of two orthogonal streets. It is known that all the members of the program committee walk only along the streets, because it is more pleasant to walk on sidewalks than on small courtyard paths. Of course, when walking from one house to another, they always choose the shortest way. All the members of the program committee visit each other equally often. Input The first line contains the number n of members of the program committee (2 ≤ n ≤ 105). The i-th of the following n lines contains space-separated coordinates xi, yi of the house of the i-th member of the program committee (1 ≤ xi, yi ≤ 106). All coordinates are integers. Output Output the average distance, rounded down to an integer, that a member of the program committee walks from his house to the house of his colleague.
