题意:给定一个模式串和文本,要求删除所有模式串.可能删除后会形成新的模式串,必须全部删除. 思路1:kmp算法求得失配数组,用一个match数组记录文本串中第i字符和未删除的字符能匹配模式串的长度.这样每次删除字符串之后就不用再匹配,直接查询match数组即可.用栈模拟,自己实现的栈可以加快速度. AC代码 #include <cstdio> #include <cmath> #include <cctype> #include <bitset> #incl…

题意:找出字符串p中的w串删除,反复操作,直到找不到w,输出这个串 思路:哈希处理前缀和,如果值相同就删掉. 代码: #include<iostream> #include<algorithm> #include<cstdio> #include<stdio.h> #include<string.h> #include<queue> #include<cmath> #include<map> #include&…

本篇用双向链表和模拟栈混洗过程两种解答方式具体解答“栈混洗”的应用问题 有关栈混洗的定义和解释在此篇:手记-栈与队列相关 列车调度(Train) 描述 某列车调度站的铁道联接结构如Figure 1所示. 其中,A为入口,B为出口,S为中转盲端.所有铁道均为单轨单向式:列车行驶的方向只能是从A到S,再从S到B:另外,不允许超车.因为车厢可在S中驻留,所以它们从B端驶出的次序,可能与从A端驶入的次序不同.不过S的容量有限,同时驻留的车厢不得超过m节. 设某列车由编号依次为{1, 2, ..., n}…

请用LinkedList模拟栈数据结构的集合,并测试 题目的意思是: 你自己的定义一个集合类,在这个集合类内部可以使用LinkedList模拟. package cn_LinkedList; import java.util.LinkedList; public class MyStack { //定义一个LinkedList类的成员变量 private LinkedList list = null; /** * 构造方法 * @list 调用LinkedList类的方法 */ public M…

思路:刚开始用STL中的栈,一直RE……,之后改为手动模拟栈操作,在注意点细节就可以了!!! 代码如下: #include<cstdio> #include<cstring> #include<algorithm> #define M 1000001 using namespace std; int A[M],B[M],a[M],s[M],cur,x,q,l,r; char c; int main() { while(scanf("%d",&…

用Python模拟栈和队列主要是利用List,当然也可以使用collection的deque.以下内容为栈: #! /usr/bin/env python # DataStructure Stack class Stack: def __init__(self, data=None): if data is not None: self.stk = [data] self.top = 0 else: self.stk = [] self.top = -1 def __str__(self): r…
