题目链接:https://vjudge.net/problem/UVA-11988 题目大意: 键盘的home键和end键出现了问题. 在输入一段文本时,home键或end键可能会自动被按下,home键会使光标移动到文章开头,end键会使光标移动到文章结尾. 输入包含多组数据,每组数据一行,包含不超过100000个字母,表示输入文本.[表示home键按下,]表示end键按下. 对每组输入输出一行,表示你在显示屏上看到的文本. Sample Input This_is_a_[Beiju]_text…

链表的思想很简单,要做到活用也不难.一般我是这样做得,从实际问题出发,先高度的概括符不符合链表的特点.能不能用链表简单解决.接着,就是编码.链表编码要理清细节性思路,最好是简单的画下图,正如改题的链表,本质上是循环链表.last指向最后一个节点.其next指针一定指向头节点.我们把s[0]当做头节点.                            last = cur = 0;         next[0] = 0;                                   …

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]…

向量和数组的优势是可以随机的存取元素和在末尾添加删除元素,而当插入元素时,需要移动大量的数据,消耗大量的时间.而链表的优势是可以在O(1)删除和插入数据.所以在频繁移动元素时,可以使用链表. 分析:如果用一个数组来保存,题目中的文本随着光标位置的移动需不断的插入字符,这样会导致大量字符移动问题.解决方案是采用链表,将字符串保存在buf[1...n]中,然后用next[i]表示下标为i的字符的下一个位置的下标(链表不一定用指针实现).为了方便起见,用一个虚拟的next[0]指向显示屏最右边的字符下…
