本题直接对每个区间取并,若出现非法区间就是No 否则就是Yes #include<bits/stdc++.h> using namespace std; #define lowbit(x) ((x)&(-x)) typedef long long LL; LL t[], l[], h[]; void run_case() { int n; LL m; cin >> n >> m; ; i <= n; ++i) cin >> t[i] >&…

维护一区间 \([l,r]\) 人按照时间升序 考虑 \((l_i, h_i, t_i)\),当前的所有区间与这个区间取交 推到 \(t_{i+1}\) 时,所有区间的端点向两边扩张即可 注意把空掉的区间删掉 #include <bits/stdc++.h> using namespace std; const int N = 105; int q,n,m,t[N],l[N],h[N]; struct interval { int l,r; void cut(int ql,int qr) {…

Codeforces Round #620 (Div. 2) A. Two Rabbits 题意 两只兔子相向而跳,一只一次跳距离a,另一只一次跳距离b,每次同时跳,问是否可能到同一位置 题解 每次跳相对距离减少Δ=(a+b)\Delta=(a+b)Δ=(a+b),如果总距离是Δ\DeltaΔ的倍数,就证明可以到同一位置 代码 #include<iostream> #include<cstdio> using namespace std; int main() { long N,x…

对于 3D 机房来说,监控已经不是什么难事,不同的人有不同的做法,今天试着用 HT 写了一个基于 HTML5 的机房,发现果然 HT 简单好用.本例是将灯光.雾化以及 eye 的最大最小距离等等功能在 3D 机房中进行的一个综合性的例子.接下来我将对这个例子的实现进行解析,算是自己对这个例子的一个总结吧.整个例子因为没有设计师的参与,所以样式上可能比较简陋,但是在一些细节的地方,比如墙上的贴图.门框嵌入以及灭火器等等,都是尽可能地还原真实的场景,也是花了些心思做这个例子的! 本例地址:http:…

命令模式是我们能够实现发送者和接收者之间的完全解耦,发送者是调用操作的对象,而接收者是接收请求并执行特定操作的对象.通过解耦,发送者无需了解接收者的接口.在这里,请求的含义是需要被执行的命令. 作用 将一个请求封装为一个对象,从而使你可用不同的请求对客户进行参数化:对请求排队或记录请求日志,以及支持可撤销的操作.当将客户的单个请求封装成对象以后,我们就可以对这个请求存储更多的信息,使请求拥有更多的能力:命令模式能够把请求发送者和接收者解耦,使得命令发送者不用去关心请求将以何种方式被处理. 类视图…
