二分时检查最大权值/最小精度会不会炸double

多组数据最好不要memset，用for(int i=1;i<=n;i++) 来清0 （Sakuya）

特判continue那一部分记得要加数组清0（Sakuya）

一道题更改做法的时候记得查看数组大小是否符合（2020.10.6 Grammy）

在写一个需要比较多的分类讨论程序时，先写导出的结果一定是正确的分类部分，最后再else printf("...\n")（有可能是yes或者no）。这样可以尽量不漏情况。
（2020.10.17 Sakuya，参见2020省赛F）

赛前不要乱吃东西，避免比赛时长时间掉线。

多组数据字符串数组的清空问题，字符串末尾的0，后缀数组需要两倍清空（？）

有的时候不重写是看不出问题的.jpg (CERC 17)

判线段和圆/和多边形相交是没有板子的，注意不要判成直线和圆/和多边形相交（这个osc写出两次这种代码了

直线的一般式转两点表示要用点向式来过渡

lwn_16：我出门的第一个想出来的题一般会不太冷静，很容易漏情况或者出假做法（好像打了一年都没怎么缓解呢 2021.6.12）

lwn_16：数论题写完了之后的对拍方法不只有写个暴力，还可以输入1e10、(1e10)-1得到答案求差来跟手动算对拍（可以用来检查取模）

线性基不break调一年。。

剪贴板

二分时检查最大权值/最小精度会不会炸double

多组数据最好不要memset，用for(int i=1;i<=n;i++) 来清0 （Sakuya）

特判continue那一部分记得要加数组清0（Sakuya）

一道题更改做法的时候记得查看数组大小是否符合（2020.10.6 Grammy）

在写一个需要比较多的分类讨论程序时，先写导出的结果一定是正确的分类部分，最后再else printf("...\n")（有可能是yes或者no）。这样可以尽量不漏情况。

（2020.10.17 Sakuya，参见2020省赛F）

赛前不要乱吃东西，避免比赛时长时间掉线。

多组数据字符串数组的清空问题，字符串末尾的0，后缀数组需要两倍清空（？）

有的时候不重写是看不出问题的.jpg (CERC 17)

判线段和圆/和多边形相交是没有板子的，注意不要判成直线和圆/和多边形相交（这个osc写出两次这种代码了

直线的一般式转两点表示要用点向式来过渡

lwn_16：我出门的第一个想出来的题一般会不太冷静，很容易漏情况或者出假做法（好像打了一年都没怎么缓解呢 2021.6.12）

lwn_16：数论题写完了之后的对拍方法不只有写个暴力，还可以输入1e10、(1e10)-1得到答案求差来跟手动算对拍（可以用来检查取模）

线性基不break调一年。。
