Robert is a famous engineer. One day he was given a task by his boss. The background of the task was the following: Given a map consisting of square blocks. There were three kinds of blocks: Wall, Grass, and Empty. His boss wanted to place as many robots as possible in the map. Each robot held a laser weapon which could shoot to four directions (north, east, south, west) simultaneously. A robot had to stay at the block where it was initially placed all the time and to keep firing all the time. The laser beams certainly could pass the grid of Grass, but could not pass the grid of Wall. A robot could only be placed in an Empty block. Surely the boss would not want to see one robot hurting another. In other words, two robots must not be placed in one line (horizontally or vertically) unless there is a Wall between them. Now that you are such a smart programmer and one of Robert's best friends, He is asking you to help him solving this problem. That is, given the description of a map, compute the maximum number of robots that can be placed in the map. Input The first line contains an integer T (<= 11) which is the number of test cases. For each test case, the first line contains two integers m and n (1<= m, n <=50) which are the row and column sizes of the map. Then m lines follow, each contains n characters of '#', '', or 'o' which represent Wall, Grass, and Empty, respectively. Output For each test case, first output the case number in one line, in the format: "Case :id" where id is the test case number, counting from 1. In the second line just output the maximum number of robots that can be placed in that map.

Shifts in China’s Rural and Urban Population: 2000-2020 The bar chart clearly reveals that from 2000 to 2020, while the total population in China increased moderately from 1.25 billion to 1.41 billion, population in urban and rural areas experienced dramatic shifts in different directions. Urban population rose from 450 million in 2000 to 670 million in 2010 and 900 million in 2020; contrastingly, rural population declined from 800 million in 2000 to 680 million in 2010 and 510 million in 2020. The population gap narrowed largely because of the joint effects of urbanization, unequal economic opportunities in rural and urban areas, and the expansion of higher education. In the first place, there was a large-scale urban sprawl during this period. Places which had been part of the vast countryside were incorporated into cities, causing hundreds of millions of rural dwellers to be passively transformed into urban residents. What’s more, while urban living standards improved greatly in these years, few economic opportunities fell on rural areas and most peasant families remained at the poverty line. Poverty prompted the call for change, leading a large quantity of healthy young peasants to leave their hometowns and flock to cities for a better living. Last but not least, China’s higher education grew at an unprecedented rate in these years. More high school graduates than ever before entered colleges and universities, most of whom preferred to stay in urban areas after graduation for personal development. The increase in urban population was a sure indication of economic and educational achievements in China. It benefited the country in many aspects, relieving the shortage of labor force in cities, lessening the burden of peasants to support their families, and affording young people from rural areas more opportunities to display their talents. However, the migration of rural residents into urban areas inevitably brought about disadvantages. Some of them, such as waste of arable land and left-behind children in the countryside, as well as traffic congestion and soaring housing prices in cities, have already called the attention of the government and corresponding measures have begun to take effect. But others, especially the inability of many peasants to integrate into urban life due to their lack of education and civilized habits, have long been neglected. In this sense, we cannot be satisfied with the superficially optimistic figures in the chart, but should endeavor to foster the integration of these newcomers by providing them with adequate assistance in educational and cultural aspects, so that they can find easier access to the prosperity and convenience of urban life and be more fully devoted to the development of cities.翻译成英文版两百单词左右的文章

Create a function pixel_flip(lst, orig_lst, budget, results, i=0) that uses recursion to generate all possible new unique images from the input orig_lst, following these rules: • The input lst is the current list being processed. Initially, this will be the same as orig_lst which is the original flattened image. • The input budget represents the number of pixels that can still be flipped. When the budget reaches 0, no more pixels can be flipped. • The input results is a list of resulting flattened images with flipped pixels. Initially, this will be an empty list. • The input i represents the index of the pixel being processed, by default set to 0, which is used to drive the recursive function towards its base case (i.e., initially starting from i=0). At termination of the function, the argument results should contain all possibilities of the input orig_lst by only flipping pixels from 0 to 1 under both the budget and the adjacency constraints. fill code at #TODO def pixel_flip(lst: list[int], orig_lst: list[int], budget: int, results: list, i: int = 0) -> None: """ Uses recursion to generate all possibilities of flipped arrays where a pixel was a 0 and there was an adjacent pixel with the value of 1. :param lst: 1D list of integers representing a flattened image . :param orig_lst: 1D list of integers representing the original flattened image. :param budget: Integer representing the number of pixels that can be flipped . :param results: List of 1D lists of integers representing all possibilities of flipped arrays, initially empty. :param i: Integer representing the index of the pixel in question. :return: None.

C语言数组操作:高度检查器编程实践

资源摘要信息: "C语言编程题之数组操作高度检查器" C语言是一种广泛使用的编程语言,它以其强大的功能和对低级操作的控制而闻名。数组是C语言中一种基本的数据结构,用于存储相同类型数据的集合。数组操作包括创建、初始化、访问和修改元素以及数组的其他高级操作,如排序、搜索和删除。本资源名为“c语言编程题之数组操作高度检查器.zip”,它很可能是一个围绕数组操作的编程实践,具体而言是设计一个程序来检查数组中元素的高度。在这个上下文中,“高度”可能是对数组中元素值的一个比喻,或者特定于某个应用场景下的一个术语。 知识点1:C语言基础 C语言编程题之数组操作高度检查器涉及到了C语言的基础知识点。它要求学习者对C语言的数据类型、变量声明、表达式、控制结构(如if、else、switch、循环控制等)有清晰的理解。此外,还需要掌握C语言的标准库函数使用,这些函数是处理数组和其他数据结构不可或缺的部分。 知识点2:数组的基本概念 数组是C语言中用于存储多个相同类型数据的结构。它提供了通过索引来访问和修改各个元素的方式。数组的大小在声明时固定,之后不可更改。理解数组的这些基本特性对于编写有效的数组操作程序至关重要。 知识点3:数组的创建与初始化 在C语言中,创建数组时需要指定数组的类型和大小。例如,创建一个整型数组可以使用int arr[10];语句。数组初始化可以在声明时进行,也可以在之后使用循环或单独的赋值语句进行。初始化对于定义检查器程序的初始状态非常重要。 知识点4:数组元素的访问与修改 通过使用数组索引(下标),可以访问数组中特定位置的元素。在C语言中,数组索引从0开始。修改数组元素则涉及到了将新值赋给特定索引位置的操作。在编写数组操作程序时,需要频繁地使用这些操作来实现功能。 知识点5:数组高级操作 除了基本的访问和修改之外,数组的高级操作包括排序、搜索和删除。这些操作在很多实际应用中都有广泛用途。例如,检查器程序可能需要对数组中的元素进行排序,以便于进行高度检查。搜索功能用于查找特定值的元素,而删除操作则用于移除数组中的元素。 知识点6:编程实践与问题解决 标题中提到的“高度检查器”暗示了一个具体的应用场景,可能涉及到对数组中元素的某种度量或标准进行判断。编写这样的程序不仅需要对数组操作有深入的理解,还需要将这些操作应用于解决实际问题。这要求编程者具备良好的逻辑思维能力和问题分析能力。 总结:本资源"c语言编程题之数组操作高度检查器.zip"是一个关于C语言数组操作的实际应用示例,它结合了编程实践和问题解决的综合知识点。通过实现一个针对数组元素“高度”检查的程序,学习者可以加深对数组基础、数组操作以及C语言编程技巧的理解。这种类型的编程题目对于提高编程能力和逻辑思维能力都有显著的帮助。

基于Swift开发的嘉定单车LBS iOS应用项目解析

资源摘要信息:"嘉定单车汇(IOS app).zip" 从标题和描述中,我们可以得知这个压缩包文件包含的是一套基于iOS平台的移动应用程序的开发成果。这个应用是由一群来自同济大学软件工程专业的学生完成的,其核心功能是利用位置服务(LBS)技术,面向iOS用户开发的单车共享服务应用。接下来将详细介绍所涉及的关键知识点。 首先,提到的iOS平台意味着应用是为苹果公司的移动设备如iPhone、iPad等设计和开发的。iOS是苹果公司专有的操作系统,与之相对应的是Android系统,另一个主要的移动操作系统平台。iOS应用通常是用Swift语言或Objective-C(OC)编写的,这在标签中也得到了印证。 Swift是苹果公司在2014年推出的一种新的编程语言,用于开发iOS和macOS应用程序。Swift的设计目标是与Objective-C并存,并最终取代后者。Swift语言拥有现代编程语言的特性,包括类型安全、内存安全、简化的语法和强大的表达能力。因此,如果一个项目是使用Swift开发的,那么它应该会利用到这些特性。 Objective-C是苹果公司早前主要的编程语言,用于开发iOS和macOS应用程序。尽管Swift现在是主要的开发语言,但仍然有许多现存项目和开发者在使用Objective-C。Objective-C语言集成了C语言与Smalltalk风格的消息传递机制,因此它通常被认为是一种面向对象的编程语言。 LBS(Location-Based Services,位置服务)是基于位置信息的服务。LBS可以用来为用户提供地理定位相关的信息服务,例如导航、社交网络签到、交通信息、天气预报等。本项目中的LBS功能可能包括定位用户位置、查找附近的单车、计算骑行路线等功能。 从文件名称列表来看,包含的三个文件分别是: 1. ios期末项目文档.docx:这份文档可能是对整个iOS项目的设计思路、开发过程、实现的功能以及遇到的问题和解决方案等进行的详细描述。对于理解项目的背景、目标和实施细节至关重要。 2. 移动应用开发项目期末答辩.pptx:这份PPT文件应该是为项目答辩准备的演示文稿,里面可能包括项目的概览、核心功能演示、项目亮点以及团队成员介绍等。这可以作为了解项目的一个快速入门方式,尤其是对项目的核心价值和技术难点有直观的认识。 3. LBS-ofo期末项目源码.zip:这是项目的源代码压缩包,包含了完成单车汇项目所需的全部Swift或Objective-C代码。源码对于理解项目背后的逻辑和实现细节至关重要,同时也是评估项目质量、学习最佳实践、复用或扩展功能的基础。 综合上述信息,"嘉定单车汇(IOS app).zip"不仅仅是一个应用程序的压缩包,它还代表了一个团队在软件工程项目中的完整工作流程,包含了项目文档、演示材料和实际编码,为学习和评估提供了一个很好的案例。
