Content Description

《算法竞赛入门经典：训练指南》是《算法竞赛入门经典》的重要补充，旨在补充原书中没有涉及或者讲解得不够详细的内容，从而构建一个较完整的知识体系，并且用大量有针对性的题目，让抽象复杂的算法和数学具体化、实用化。本书共6章，分别为算法设计基础、数学基础、实用数据结构、几何问题、图论算法与模型和更多算法专题，全书通过近200道例题深入浅出地介绍了上述领域的各个知识点、经典思维方式以及程序实现的常见方法和技巧，并在章末和附录中给出了丰富的分类习题，供读者查漏补缺和强化学习效果。本书题目多选自近年来ACM/ICPC区域赛和总决赛真题，内容全面，信息量大，覆盖了常见算法竞赛中的大多数细分知识点。书中还给出了所有重要的经典算法的完整程序，以及重要例题的核心代码，既适合选手自学，也方便教练组织学习和训练。

Book Abstract

【输入格式】
输入包含多组数据。每组数据的第一行为学生个数n（1≤n≤500000）；以下每行包含两个不同的非负整数A和B，表示该学生想从A学校换到B学校。输入结束标志为n=0。
【输出格式】
对于每组数据，输出YES或者NU。
复合词（Compound Words，UVa 10391）
给定一个词典，要求找出其中所有的复合词，即恰好由两个单词连接而成的单词。
【输入格式】
输入只有一组数据，其中每行都是一个由小写字母组成的单词。输入已按照字典序排序，且不超过120000个单词。
【输出格式】
输出所有复合词，按照字典序排列。
Gergovia的酒交易（Wire trading in Gergovia，UVa 11054）
直线上有n个等距的村庄，每个村庄要么买酒，要么卖酒。把k个单位的酒从一个村庄运到相邻村庄需要k个单位的劳动力。问最少需要多少劳动力才能满足所有村庄的需求。
【输入格式】
输入包含多组数据。每组数据的第一行为村庄个数n（2≤n≤100000）；第二行从左到右给出各个村庄对酒的需求ai（—1000≤a≤1000），其中ai>0表示买酒，ai<0表示卖酒。输入保证所有ai之和等于0。输入结束标志为n=0。
【输出格式】
输出劳动力总和的最小值。输出保证在64位带符号整数的范围内。
平均值（Average，Seoul 2009，LA 4726）
给定一个长度为n的01序列，选一个长度至少为L的连续子序列，使得子序列中数字的平均值最大。如果有多解，子序列长度应尽量小；如果仍有多解，起点编号应尽量小。序列中的字符编号为1～n，因此[I，n]就是指完整的序列。
例如，对于长度为17的序列00101011011011010，如果L=7，子序YU[7，14]的平均值最大，为6／8（它的长度为8）；如果L=5，子序列[7，11]的平均值最大，为4／5。
【输入格式】
输入的第一行为数据组数T。每组数据的第一行为两个整数胛和L（1≤n≤100000，1≤L≤1000），第二行为一个长度为n的01序列。
【输出格式】
对于每组数据，输出满足条件的最优子序列的起点和终点编号。
餐厅（Restaurant，Deajon，2010，LA4851）
有一个M×M的网格，左下角坐标为（0，0），右上角坐标为（M—1，M—1）。网格里有两个y坐标相同的宾馆A和B，以及n个餐厅。宾馆A和宾馆B里各有一个餐厅，编号为1和2，其他地方的餐厅编号为3～n。现在你打算开一家新餐厅，需要考查一下可能的位置。
