先过了L傻逼题，hr推了个<math>\frac{n!n!}{n^n}</math> 暴力用py艹过去了，py写了一万年，我是不是该看看py小数和分数文档了 | |||
后来想到是不是一直<math> ans / i / i * n</math> c++ 也能过啊 | 后来想到是不是一直<math> ans / i / i * n</math> c++ 也能过啊 | ||

感觉柿子推得是不是有点慢啊，lzw感觉一开始推柿子完全不在线啊 | 感觉柿子推得是不是有点慢啊，lzw感觉一开始推柿子完全不在线啊 | ||

比赛来晚了QAQ | |||
来了之后被蓝总喂了一发错误的题意，手摸样例才发现不太对劲 | |||
重新读题后想了想算贡献的做法，推出来柿子，发现数据范围有一点大，于是蓝总选择用py写 | |||
接下来是一道sb模拟，嗯，没啥可说的 | |||
然后是社会主义FFT，在蓝总的强烈暗示下，我用一万年才写出了个多项式乘积的柿子，感觉好像是对的，经过蓝总精细的coding手法，一发A了！ | |||
然后是一道构造题，蓝总提出偶数构造方案后，我心想奇数构造方案也差不多啊，应该不需要我跟蓝总说出来吧（逃 | |||
收获：以后不👁队友了，想好了跟队友说就行，相互确认思路 | |||
