题目地址:P1456 Monkey King 一道挺模板的左偏树题 不会左偏树?看论文打模板,完了之后再回来吧 然后你发现看完论文打完模板之后就可以A掉这道题不用回来了 细节见代码 #include <bits/stdc++.h> using namespace std; const int N = 1e5 + 6; int n, m, f[N], a[N], l[N], r[N], d[N]; //类并查集路径压缩 int get(int x) { if (x == f[x]) return…

并查集+左偏树.....合并的时候用左偏树,合并结束后吧父结点全部定成树的根节点,保证任意两个猴子都可以通过Find找到最厉害的猴子                       Monkey King Time Limit: 10000MS   Memory Limit: 32768KB   64bit IO Format: %lld & %llu [Submit]   [Go Back]   [Status] Description Once in a forest, there lived…

我们知道如果要我们给一个序列排序,按照某种大小顺序关系,我们很容易想到优先队列,的确很方便,但是优先队列也有解决不了的问题,当题目要求你把两个优先队列合并的时候,这就实现不了了 优先队列只有插入 删除 取数的操作,但是却没有合并两个优先队列的操作. 这也是它的局限所在. 本次要介绍的左偏树拥有优先队列的所有功能,同时它还可以合并操作.  树的复杂度都比较低,一般log(n)就够了,左偏树也是如此,左偏树如果一个个结点暴力插入复杂度最大为nlog(n) 还有一种仿照二叉树的算法,这里不做介绍. …
