排序模拟枚举 算法

1.排序模拟枚举

复杂度

一般（最坏）复杂度 ：记号为 O(……) 均摊复杂度 $\qquad\quad\,$ ：记号为 Θ(……),但一般写成O(……)

约定

例题 校门外的树

思路：可以建一个数组，保存地铁每一个位置的情况，每次输入l,r，就把这个数组[l,r]部分都变成1，最后再统计有多少0即可

代码如下（勿喷）

#include <iostream> using namespace std; const int maxn = 10010; int tree[maxn]; int main(void) { int l,m,b,e,ans = 0; cin>>l>>m; for(int i = 0;i < m;i++) { cin>>b>>e; for(int j = b;j <= e;j++) tree[j] = 1; } for(int i = 0;i <= l;i++) ans+=!tree[i]; cout<<ans; }

枚举

枚举，顾名思义，就是把所有可能的情况都试一遍直到找到正确的答案。

例题 P1219 八皇后

【题目描述】

一个如下的 $6×6$ 的跳棋棋盘，有六个棋子被放置在棋盘上，使得每行、每列有且只有一个，每条对角线（包括两条主对角线的所有平行线）上至多有一个棋子。 上面的布局可以用序列$2\ 4\ 6\ 1\ 3\ 5$来描述，第 $i$ 个数字表示在第 $i$ 行的相应位置有一个棋子，如下：

行号 $1\ 2\ 3\ 4\ 5\ 6$

列号 $2\ 4\ 6\ 1\ 3\ 5$

这只是棋子放置的一个解。请编一个程序找出所有棋子放置的解。 并把它们以上面的序列方法输出，解按字典顺序排列。 请输出前 $3$ 个解。最后一行是解的总个数。 【输入格式】 一行一个正整数 $n$，表示棋盘是 $n \times n$ 大小的。 【输出格式】 前三行为前三个解，每个解的两个数字之间用一个空格隔开。第四行只有一个数字，表示解的总数。 输入输出样例

输入 #1 $\qquad\qquad\qquad$ 输出 #1

letter 3 pt 2

[heh so my attention span is shit and i love music and her taste is really good i have no regrets]

so anyhow. you might be wondering how i’m doing today?

or not. that was what you were potentially-wondering last letter. wondering WHAT i’m doing today, then. aside from getting sidetracked by music recommendations.

i’m kinda nervous because of the summer class, it’s starting monday and my eyesight is shit so i won’t be able to see anything on a board, and i don’t have a device that i can use to take pictures. i can hopefully ask leisha though, if she’s not off talking to people she knows :/

maybe i’ll make new friends though, that’d be pretty cool beans.

anyways, hm. i’ve been very focused on music lately. i wanna learn guitar, man. so bad. and maybe piano too. congcong plays piano and morgan knows guitar so that’s pretty convenient there. 

morgan also has a butterfly knife, which is hella cool beans. i know a little of how to do a couple tricks on it but also the space between my first two knuckles is still bruised and it’s been over a week since i killed it. not a fun experience, man. it’s still hella cool though. 

i’ve been trying to go for a lot of coding each day, also. not sure how well it’s working though. i’ve gotten six hours done and it’s been like a week :/

they wanna get me into the usaco training camp thing, so i can also teach and get a job next summer. i really want a job man.

How does USACO work? Do you have to do all the training problems to be able to participate?

Response from Flitwick: 

There are no requirements for participation - just create an account with their website and you can just go ahead and do it. The training problems help immensely with the contest, but you by no means have to do them. Good luck with the contests!
