== 最重要的事情 ==
'''写题前要把算法冷静的想清楚，不能慌着写！多花5分钟理清细节！ by 张清棋'''
'''最后一刻的调试依然要沉着冷静，不能心慌。欲速则不达！ by 张清棋'''
== 定个小目标 ==
~~~校赛rank前3（所有队伍中）~~~ '''实际rank 9'''
省赛rank前3（所有队伍中）：发挥团队最高水平
== 杂事杂项 ==
* [wiki::makefile makefile]
* [wiki::模板整理 板子整理]
* 用std::endl会T成sb.
* 一般无向图搞的是生成森林而不是生成树.
* 用scanf("%[!^\n]\n",s)可以windows下读一行,但存在读不了空行的问题.linux好像不能用,老实读getchar()最稳.
* '''抄板子'''注意“1”和“l”的区别，尽量不要修改代码风格，按原样抄
* 浮点数转整数要加eps
* 交流题意和读题的注意
1. 要把题目范围看清楚，每个变量的范围都要告诉写题的队友
2. 要把特殊性质全部告诉队友。听题意的队友应该问任何不太清楚的地方。
3. 如果是简单的模拟，直接叫lyk写，自己再读题，防止交流出错
4. 要学会根据过的人数预估难度，从而猜测正确的题意。读到NP问题或者复杂的问题，一定要看题目的特殊限制
5. 读完题要'''正确的模拟'''样例，注意样例解释在最后一页不要漏掉
* 注意scanf/printf的格式不要写错
* 不要使用重复的变量名
* 不要异想天开脑补出STL存在某些不合理的操作
* 相信网络流,尽管它的复杂度是O(n^3^)
* '''不要被题目时限迷惑！'''经常有10w nlogn或者100w O(n)的题目出到4s ，甚至10s！还是应该全面的检查自己算法的正确性和是否可以简化
* opentrains和codeforces上任何手动编译优化和register都没有用。不要想着优化常数的黑科技
* opentrains比本机慢2.5倍左右：本机1s，上面大概2.5s
* codeforces比opentrains快，比本机略微慢一点，比zqq的电脑慢两倍
* '''出题人一般不会卡常。要注意优化算法，而非常数'''
* '''带符号数的移位运算符是UB的''',遇到奇怪的结果不需要慌.
* int tarjan(int x) 需要返回值的函数没有返回值会MLE
* 精度，这个玄学的东西，我们已经踩了一次又一次坑了。我觉得'''首先需要理论的了解、并且主干知识应该三个人都达成共识（比如数值分析）'''，这样，才不会因为精度而争吵。其次，遇到的坑真的要记下来。怎么解决问题，避免误差，怎样的误差是可以接受的，可以让我我们少走很多弯路。'''系统的学习和经验总结，相信一定可以对我们三个人对精度的认识有所提升'''，至于怎么学习，还要去了解和探索。
* 单组数据的二分/三分设步数不设eps,多组数据看情况
* 一个变量>前缀和>树状数组>st表>线段树,尽量不要一上来无脑线段树
* C++整数除法取整总是取接近0的
* 打表要趁早
* 相对误差要用 < max(1., abs(x)) * eps 判
* vector的resize , clear操作都是线性的。用vector的指针要用.data(), 可以用.swap在常数时间内交换。不熟悉的时候不要乱用操作，不要删除迭代器。
* 参数 g++ *.cpp -o * -O2 -fno-stack-limit -std=c++11 -Wextra -Wall -Wconversion -fsanitize=undefined -fsanitize=address

最重要的事情
写题前要把算法冷静的想清楚，不能慌着写！多花5分钟理清细节！ by 张清棋
最后一刻的调试依然要沉着冷静，不能心慌。欲速则不达！ by 张清棋
定个小目标
~校赛rank前3（所有队伍中）~ 实际rank 9
省赛rank前3（所有队伍中）：发挥团队最高水平
杂事杂项
- makefile
- 板子整理
- 用std::endl会T成sb.
- 一般无向图搞的是生成森林而不是生成树.
- 用scanf("%[!^\n]\n",s)可以windows下读一行,但存在读不了空行的问题.linux好像不能用,老实读getchar()最稳.
- 抄板子注意“1”和“l”的区别，尽量不要修改代码风格，按原样抄
- 浮点数转整数要加eps
- 交流题意和读题的注意
1. 要把题目范围看清楚，每个变量的范围都要告诉写题的队友
2. 要把特殊性质全部告诉队友。听题意的队友应该问任何不太清楚的地方。
3. 如果是简单的模拟，直接叫lyk写，自己再读题，防止交流出错
4. 要学会根据过的人数预估难度，从而猜测正确的题意。读到NP问题或者复杂的问题，一定要看题目的特殊限制
5. 读完题要正确的模拟样例，注意样例解释在最后一页不要漏掉
- 注意scanf/printf的格式不要写错
- 不要使用重复的变量名
- 不要异想天开脑补出STL存在某些不合理的操作
- 相信网络流,尽管它的复杂度是O(n3)
- 不要被题目时限迷惑！经常有10w nlogn或者100w O(n)的题目出到4s ，甚至10s！还是应该全面的检查自己算法的正确性和是否可以简化
- opentrains和codeforces上任何手动编译优化和register都没有用。不要想着优化常数的黑科技
- opentrains比本机慢2.5倍左右：本机1s，上面大概2.5s
- codeforces比opentrains快，比本机略微慢一点，比zqq的电脑慢两倍
- 出题人一般不会卡常。要注意优化算法，而非常数
- 带符号数的移位运算符是UB的,遇到奇怪的结果不需要慌.
- int tarjan(int x) 需要返回值的函数没有返回值会MLE
- 精度，这个玄学的东西，我们已经踩了一次又一次坑了。我觉得首先需要理论的了解、并且主干知识应该三个人都达成共识（比如数值分析），这样，才不会因为精度而争吵。其次，遇到的坑真的要记下来。怎么解决问题，避免误差，怎样的误差是可以接受的，可以让我我们少走很多弯路。系统的学习和经验总结，相信一定可以对我们三个人对精度的认识有所提升，至于怎么学习，还要去了解和探索。
- 单组数据的二分/三分设步数不设eps,多组数据看情况
- 一个变量>前缀和>树状数组>st表>线段树,尽量不要一上来无脑线段树
- C++整数除法取整总是取接近0的
- 打表要趁早
- 相对误差要用 < max(1., abs(x)) * eps 判
- vector的resize , clear操作都是线性的。用vector的指针要用.data(), 可以用.swap在常数时间内交换。不熟悉的时候不要乱用操作，不要删除迭代器。
- 参数 g++ *.cpp -o * -O2 -fno-stack-limit -std=c++11 -Wextra -Wall -Wconversion -fsanitize=undefined -fsanitize=address
- 热身赛试机
- 待学习的东西
- head
