破损的键盘(悲剧文本)(Broken Keyboard(a.k.a. Beiju Text),Uva 11988) 题意描述 你在输入文章的时候,键盘上的Home键和End键出了问题,会不定时的按下.你却不知道此问题,而是专心致志地打稿子,甚至显示器都没开.当你打开显示器之后,展现你面前的数一段悲剧文本.你的任务是在显示器打开前计算出这段悲剧的文本. 给你一段按键的文本,其中'['表示Home键,']'表示End键,输入结束标志是文件结束符(EOF). 样例输入 This_is_a_[Beiju…

题目链接:https://vjudge.net/problem/UVA-11988 题目大意:输入一个字符串,输出在原本应该是怎么样的?  具体方法是 碰到' [ ' 回到最前面  碰到‘ ]’  回到最后面. 思路:很容易可以想到用数组来写,但是仔细分析一下,每次你把一个字符插入到最前面,它后面的字符全都要往后移,那么复杂度是多大呢?  最差的情况,每一个都插在最前面,呢么复杂度是 n*n   肯定超时的.  应用链表则只有n的复杂度了.  这是我接触到的第一道链表题目,说的详细一点: 比如 …

题意: 模拟一个文本编辑器,可以输入字母数字下划线,如果遇到'['则认为是Home键,如果是']'则认作End键. 问最终屏幕上显示的结果是什么字符串. 分析: 如果在数组用大量的移动字符必然很耗时.所以next数组表示显示屏中s[i]右边的字符编号,变量cur模拟光标,即当前光标位于s[cur]的右边. 变量last记录显示屏最后一个字符的下标. 我理解的连接的情况应该是这样子的: //#define LOCAL #include <cstdio> #include <cstring&…

一开始不懂啊,什么Home键,什么End键,还以为相当于括号,[]里的东西先打印出来呢.后来果断百度了一下. 悲催啊... 题意:给定一个字符串,内部含有'['和']'光标转移指令,'['代表光标移向文章头,']'代表光标移向文章尾,问最终在屏幕上显示的字符串序列是什么 思路:直接模拟一下即可,不过因为由于会可能移动到字符串开头以及结尾,所以我开了3个char数组. str1存储由于'['的原因而打印在开头的字符,str3存储由于']'的原因打印在结尾的字符,str2则是存储一开始在没遇到'['…

刘汝佳的题目,悲剧文本 -_-||| 这里使用vector<string>容器倒置记录数据,然后从后面输出就能够了. 难度就是不知道这种文档究竟哪里是開始输出,故此使用动态管理内存的容器比較好做. 添加了io处理的O(n)算法也没有上榜,郁闷. #include <stdio.h> #include <vector> #include <string> using std::vector; using std::string; const int MAX_B…

题目描述: 题目思路: 1.使用链表来重新定位各个字符 2.用数组实现链表 3.开一个数组list[i]来存储字符数组下一个字符的位置 #include <iostream> #include <cstring> using namespace std; + ; int last,cur,list[maxn] ; char s[maxn] ; int main(int argc, char *argv[]) { ) == ) { ); last = cur = ; list[] =…

使用list来模拟就行了,如果熟悉list,那么这道题真是分分钟秒掉... list是双向循环链表,插入和删除操作非常快,缺点是不能像数组一样随机按下标读取. 一下是wiki上说明的相关函数:http://zh.wikipedia.org/wiki/List_(STL) Iterators: list.begin() 回传指向第一个元素的 Iterator. list.end() 回传指向最末元素的下一个位置的 Iterator. list.rbegin() 回传指向最末个元素的反向 Itera…

[链接] 我是链接,点我呀:) [题意] 在这里输入题意 [题解] 会链表的插入操作的话.这个就不难了. 放置两个哨兵节点. 然后模拟插入一个节点的过程就好. 实时修改光标就好->即下一个插入的位置. [代码] #include <bits/stdc++.h> using namespace std; const int N = 1e5; const int fir = 0, last = N + 10; int nex[N + 100],len,be; char s[N + 100];…

题目大意:将一个字符串改变顺序后输出.遇到“[”就将后面内容拿到最前面输出,遇到“]”就将后面的内容拿到最后面输出. 题目分析:用nxt[i]数组表示i后面的字符的下标,实际上就是以字符i为头建立链表,写法类似链式前向星. 代码如下: # include<iostream> # include<cstdio> # include<cstring> # include<algorithm> using namespace std; char p[100005]…

题目链接:https://www.luogu.org/problemnew/show/UVA11988 这题虽说是和链表有关的模拟,但其实并不是很需要啊,但蒟蒻用了(说的好听是练手,说的难听是太弱),效果海星. 分析: 此题模拟即可,本人估计难度大概提高-,可以直接数组模拟,也可以用链表存储.主要是每组数据有多组输入,所以读入的方法可以多加注意,我的这种方法海星(这么有自信是因为是跟大佬学的),然后灵魂活运用for语言即可. 其他在代码中说明. 代码: #include<iostream> #…

即将dfs()放到打印本段字符的后面 不过汝佳书上面说是用链表写的,无意中用递归写出来了,而且写的挺简单的,代码不复杂,写这个博客主要是想记住递归这种神奇的方法 平时递归搜索时候,dfs()的在其他代码的前后不同会有不同的效果,还有就是在递归前标记某一个,递归后消除这个标记(最经典的是暴力枚举排序) 在递归中也会经常遇到边递归边打印或者是全部递归之后再打印,这些各有不同 而这道题目就充分利用这个特点:递归强行的将一个代码片段或一个操作的执行顺序改变 这个题目其实不难,大概意思就是按了一个[ 就在…
