Abstract 背景： 指针分析的误差可能会对安卓app代码的信息流分析造成干扰 静态分析的最新进展表明，结合在运行时的某⼀点拍摄的动态堆快照可以显着改进⼀般静态分析 本文： 取舍因素： 在执行期间何时收集快照以及收集多少快照 快照使⽤⽅式如何影响可靠性和精度 Task:在污点分析中引
https://codeforces.com/problemset/problem/1623/C 题意：有n堆石子，第i堆石子有hi个石子，你可以从第3堆开始到第n堆，将d个石子移动到i - 1堆和2d个石子移动到i - 2堆，问最后最大的最小堆为多少。 题解：二分！！！（代码有说明！） #include<iostream> #include<algorithm> #include<cstring> #
题目 原题地址：C. Balanced Stone Heaps 题目编号：1623C 目标算法：二分查找 难度评分：1600 1.题目大意 n 堆石头 当前堆为 i （3 ≤ i ≤ n）， 共 h 个石头 可以移动 d 个石头到堆 i - 1 ，2·d 个石头到堆 i - 2 （0 ≤ 3·d ≤ h）。 当前堆的石头数为 0 是也算作一个堆。 求：移动石头后最大
Solution Another binary search! The only thing you need to take notice of is that you have to do the thing in the follewing order:3->n.But there's a paradox.If you want to know how many stones you want to give to the two heaps before the curr

本题仅仅用到堆的性质（大顶堆和小顶堆）并不涉及对堆的代码考察，实际上考察的还是完全二叉树的性质，以及通过层序遍历得到后序遍历 之前也认真写过一次，但是没有写出来；这次又试了试，过了 对于遍历，还是先记录过程中的数据；最后在main()函数里输出结果 #include <cstdio> #include <vec
题意：给出序列判断是否为最大堆/最小堆，并输出后序遍历序列 #include<bits/stdc++.h> using namespace std; int n,m; int a[10005]; int k[10005]; int sum1,sum2,sum; vector<int> v; void dfs(int index,int cnt) { if(index>n) { int p=k[0],f=k[0],p1=0,f1=0; for(
L - A Heap of Heaps CodeForces - 538F 这个是一个还比较裸的静态主席树。 这个题目的意思是把这个数组变成k叉树，然后问构成的树的子树小于等于它的父节点的对数有多少。 因为这个k是从1~n-1 所以直接暴力肯定是不对的，所以可以用主席树来查询区间第k大。 查询的次数大约为n+n
