### 1. `freopen` 写错默哀
BJ-0068
```cpp
freopen("traverse0.in", "r", stdin);
//freopen("traverse.out", "w", stdout);
```
### 2. 爱情请给予我力量
BJ-0160
```cpp
mt19937 rng1(20071019),rng2(20080416); // Love shall bring me luck.
```
### 3. cin love out
BJ-0510
```cpp
#define cin lyc
#define cout lmy
//cin love cout
```
### 4. 留名 er
BJ-0093
```cpp
/*

不知道 keatsli 写的咋样了。

```cpp
// 寄了，留个名吧，luogu id: creation_hy
// 确实挺难的，后两题正解都没什么思路，唯一可惜的是最后两个半小时就拿了44分
```
### 5. T4 怎么是元神？？？
BJ-0001
```cpp
/*
g++ t1.cpp -o t1.exe -O2 -std=c++14 -fsanitize=address,undefined -Wall -Wextra; ./t1.exe
ulimit -v (KB)
ulimit -s (KB)
后排的老哥进场先找到了蜘蛛纸牌开始打还是很绷不住的。
键盘疑似有点难用。（
traverse 怎么发了12个样例、哈人
测小数据，打对拍，Aal izz well!
***
t1：考虑贪心，能填就填
t2：8:40
考虑不行的方案：一串限制构成一个链，链的开头是一个确定的x，链的末尾是一个确定（且和指定不符）的x时不行
或者两个不同的值赋给了一个x
按照x升序，乘法原理计“好链个数”即可
g++ t2.cpp -o t2.exe -O2 -std=c++14 -fsanitize=address,undefined -Wall -Wextra; ./t2.exe
t3: 10:21 这啥玩意。？？？
t4怎么是元神？？？
好像我只会nlog^2n 急了
大样例过了！！
所以正解是nlogn还是nlog^2n草过去啊 感觉转化后的问题就是整体二分板子的说
g++ t3.cpp -o t3.exe -O2 -std=c++14 -fsanitize=address,undefined -Wall -Wextra; ./t3.exe
g++ t4.cpp -o t4.exe -O2 -std=c++14 -fsanitize=address,undefined -Wall -Wextra; ./t4.exe
g++ Sgt.cpp -o Sgt.exe -O2 -std=c++14 -fsanitize=address,undefined -Wall -Wextra -Wl,--stack=1073741824; ./Sgt.exe
别挂分啊……一道题都没有对拍（（
虽然大样例是过了的没错…

Welcome to NOIP 2024!
The Finale.
Hope I can get at least 100 points!
Also, If someone , I mean if your name starts with a C and ends wish an H.
Hello. :)
I will write my oi journey in the last of the code, but not here. I will write solutions here.
UPD: I WILL NOT THIS IS SO HARD AHHHHHH
Wow, this seems to be easy.
Given two bit-string with length of n,
Some can be operated, some can not.
Show that at most how many chars can appear in the same place.
Hmm, we can deal in these segments huh?
We found that it is same to make them pair at the beginning or at the end.
Thus, we break it down to segment first, and then...
I dunno
uhh
We define: that every segment start with a number WITHOUT edit = 0, and always ENDS WITH edit = 0.
... Harder than I thought...
Lets first break down into segments.
Oh shit what am I thinking about
just use two arrows....
Just enumerate a,
最特殊的情况，两个的间隔不超过1.
我们这样处理，每次都会有若干种状态
状态一：两个都没到箭头
状态二：下边的过了箭头，但是上边的没过
状态三：上边的过了，但是下边的没过
我好像理解了
这个东西的区间只能一直包含一个箭头，要不然太麻烦了
马的，好难调啊。
我佛了，我不调了，七年OI止步于此，没认真学导致的。

Ohhh...I think that I found the 48pts solution,but I can't debug!(big-example is to big)I can just get 24 pts(maybe less than 24).
I hadn't get level 7 in CSP-S.The level 7 is 221 pts,but I'm just 220.
I hope I can get level 7 and get into next round.
Grade 9 is to tired...I hate whk.
NOIP will stop at 13:00,but our school let us do english listen-read exam at 13:30.What can I say?(Manba out!)
Hope I will goto sdsz in grade 10.Hope I will get 1=.
My rks stop at 15.26.How can I increase it?
How can I dowaload minecraft(not netease but microsoft) in apple system?
23 minutes left......I don't know what I should do?
I think my T1 code is allright,but I can't say that my solution is right.But it AC in all big-example.
T2 is no problem,but T3&T4 I just have 56 pts.I don't think I can found right 100pts solution,but I can't find any solution that pts is higher than now.
Maybe I should preview English?No...it's impossible.
Just left 16 minutes......
Maybe I will AFO.
Love xyc forever.
