多校7 HDU5818 Joint Stacks 题意:n次操作.模拟栈的操作,合并的以后,每个栈里的元素以入栈顺序排列 思路:开三个栈,并且用到了merge函数 O(n)的复杂度 #include <bits/stdc++.h> using namespace std; #define LL long long const int inf = 0x3f3f3f3f; ; ; #define clc(a,b) memset(a,b,sizeof(a)) ; void fre() {freope…

欢迎访问~原文出处——博客园-zhouzhendong 去博客园看该题解 题目传送门 - HDU5818 题意概括 有两个栈,有3种操作. 第一种是往其中一个栈加入一个数: 第二种是取出其中一个栈的顶端数字: 第三种是将其中一个栈的所有元素放入另外一个栈,元素顺序依旧按照加入顺序来放. 题解 写一下左偏树就可以了. 按照进入的时间为权值维护两个大根堆(栈先进后出). 代码 #include <cstring> #include <cstdio> #include <cstdl…

这题合并栈让我们想到了左偏树. 我们可以维护val值为时间,dis值为size的左偏树,定义两个根root1和root2,表示两个栈的栈顶,建大根的左偏树. 接下来的插入,删除,两个栈合并都是左偏树的基本操作,直接写即可,代码里有注释. #include<bits/stdc++.h> #define maxn 100001 #define inf 0x7f7f7f7f using namespace std; int sum[maxn],ch[maxn][2],dis[maxn],root1,…
