1444. Elephpotamus Time limit: 0.5 second Memory limit: 64 MB Harry Potter is taking an examination in Care for Magical Creatures. His task is to feed a dwarf elephpotamus. Harry remembers that elephpotamuses are very straightforward and imperturbable. In fact, they are so straightforward that always move along a straight line and they are so imperturbable that only move when attracted by something really tasty. In addition, if an elephpotamus stumbles into a chain of its own footprints, it falls into a stupor and refuses to go anywhere. According to Hagrid, elephpotamuses usually get back home moving along their footprints. This is why they never cross them, otherwise they may get lost. When an elephpotamus sees its footprints, it tries to remember in detail all its movements since leaving home (this is also the reason why they move along straight lines only, this way it is easier to memorize). Basing on this information, the animal calculates in which direction its burrow is situated, then turns and goes straight to it. It takes some (rather large) time for an elephpotamus to perform these calculations. And what some ignoramuses recognize as a stupor is in fact a demonstration of outstanding calculating abilities of this wonderful, though a bit slow-witted creature. Elephpotamuses' favorite dainty is elephant pumpkins, and some of such pumpkins grow on the lawn where Harry is to take his exam. At the start of the exam, Hagrid will drag the elephpotamus to one of the pumpkins. Having fed the animal with a pumpkin, Harry can direct it to any of the remaining pumpkins. In order to pass the exam, Harry must lead the elephpotamus so that it eats as many pumpkins as possible before it comes across its footprints. Input The first input line contains the number of pumpkins on the lawn N (3 ≤ N ≤ 30000). The pumpkins are numbered from 1 to N, the number one being assigned to the pumpkin to which the animal is brought at the start of the trial. In the next N lines, the coordinates of the pumpkins are given in the order corresponding to their numbers. All the coordinates are integers in the range from −1000 to 1000. It is guaranteed that there are no two pumpkins at the same location and there is no straight line passing through all the pumpkins. Output In the first line write the maximal number K of pumpkins that can be fed to the elephpotamus. In the next K lines, output the order in which the animal will eat them, giving one number in a line. The first number in this sequence must always be 1.写一段Java完成此目的

7-3 Score Processing 分数 10 作者 翁恺 单位 浙江大学 Write a program to process students score data. The input of your program has lines of text, in one of the two formats: Student's name and student id, as <student id>, <name>, and Score for one student of one course, as <student id>, <course name>, <marks>. Example of the two formats are: 3190101234, Zhang San 3190101111, Linear Algebra, 89.5 Comma is used as the seperator of each field, and will never be in any of the fields. Notice that there are more than one word for name of the person and name of the course. To make your code easier, the score can be treated as double. The number of the students and the number of the courses are not known at the beginning. The number of lines are not known at the beginning either. The lines of different format appear in no order. One student may not get enrolled in every course. Your program should read every line in and print out a table of summary in .csv format. The first line of the output is the table head, consists fields like this: student id, name, <course name 1>, <course name 2>, ..., average where the course names are all the courses read, in alphabet order. There should be one space after each comma. Then each line of the output is data for one student, in the ascended order of their student id, with score of each course, like: 3190101234, Zhang San, 85.0, , 89.5, , , 87.3 For the course that hasn't been enrolled, leave a blank before the comma, and should not get included in the average. The average has one decimal place. There should be one space after each comma. And the last line of the output is a summary line for average score of every course, like: , , 76.2, 87.4, , , 76.8 All the number output, including the averages have one decimal place. Input Format As described in the text above. Output Format As described in the text above. The standard output is generated by a program compiled by gcc, that the round of the first decimal place is in the "gcc way". Sample Input 3180111435, Operating System, 34.5 3180111430, Linear Algebra, 80 3180111435, Jessie Zhao 3180111430, Zhiwen Yang 3180111430, Computer Architecture, 46.5 3180111434, Linear Algebra, 61.5 3180111434, Anna Teng Sample Output student id, name, Computer Architecture, Linear Algebra, Operating System, average 3180111430, Zhiwen Yang, 46.5, 80.0, , 63.2 3180111434, Anna Teng, , 61.5, , 61.5 3180111435, Jessie Zhao, , , 34.5, 34.5 , , 46.5, 70.8, 34.

Python调试器vardbg:动画可视化算法流程

资源摘要信息:"vardbg是一个专为Python设计的简单调试器和事件探查器,它通过生成程序流程的动画可视化效果,增强了算法学习的直观性和互动性。该工具适用于Python 3.6及以上版本,并且由于使用了f-string特性,它要求用户的Python环境必须是3.6或更高。 vardbg是在2019年Google Code-in竞赛期间为CCExtractor项目开发而创建的,它能够跟踪每个变量及其内容的历史记录,并且还能跟踪容器内的元素(如列表、集合和字典等),以便用户能够深入了解程序的状态变化。" 知识点详细说明: 1. Python调试器(Debugger):调试器是开发过程中用于查找和修复代码错误的工具。 vardbg作为一个Python调试器,它为开发者提供了跟踪代码执行、检查变量状态和控制程序流程的能力。通过运行时监控程序,调试器可以发现程序运行时出现的逻辑错误、语法错误和运行时错误等。 2. 事件探查器(Event Profiler):事件探查器是对程序中的特定事件或操作进行记录和分析的工具。 vardbg作为一个事件探查器,可以监控程序中的关键事件,例如变量值的变化和函数调用等,从而帮助开发者理解和优化代码执行路径。 3. 动画可视化效果:vardbg通过生成程序流程的动画可视化图像,使得算法的执行过程变得生动和直观。这对于学习算法的初学者来说尤其有用,因为可视化手段可以提高他们对算法逻辑的理解,并帮助他们更快地掌握复杂的概念。 4. Python版本兼容性:由于vardbg使用了Python的f-string功能,因此它仅兼容Python 3.6及以上版本。f-string是一种格式化字符串的快捷语法,提供了更清晰和简洁的字符串表达方式。开发者在使用vardbg之前,必须确保他们的Python环境满足版本要求。 5. 项目背景和应用:vardbg是在2019年的Google Code-in竞赛中为CCExtractor项目开发的。Google Code-in是一项面向13到17岁的学生开放的竞赛活动,旨在鼓励他们参与开源项目。CCExtractor是一个用于从DVD、Blu-Ray和视频文件中提取字幕信息的软件。vardbg的开发过程中,该项目不仅为学生提供了一个实际开发经验的机会,也展示了学生对开源软件贡献的可能性。 6. 特定功能介绍: - 跟踪变量历史记录:vardbg能够追踪每个变量在程序执行过程中的历史记录,使得开发者可以查看变量值的任何历史状态,帮助诊断问题所在。 - 容器元素跟踪:vardbg支持跟踪容器类型对象内部元素的变化,包括列表、集合和字典等数据结构。这有助于开发者理解数据结构在算法执行过程中的具体变化情况。 通过上述知识点的详细介绍,可以了解到vardbg作为一个针对Python的调试和探查工具,在提供程序流程动画可视化效果的同时,还通过跟踪变量和容器元素等功能,为Python学习者和开发者提供了强大的支持。它不仅提高了学习算法的效率,也为处理和优化代码提供了强大的辅助功能。
