\(0.\)前言有一天\(Au\)爷讲期望都见到了此题，通过写题解来加深理解。\(1.\)题意将初始为空的序列的末尾给定概率添加\(a\)或\(b\)，当至少有\(k\)对\(ab\)时停止（注意是“对”，中间可以间隔字符），求\(ab\)期望对数。\(2.\)思路通过查看标签通过阅读题面我们容易发现本题是一道期望DP，但是本题的状态并不很容易想到，设\(f[i][j]\)表示前缀中有\(i\)个\(a\)，\(j\)个\(ab\)停止后的期望个数，这样发现转移就容易了很多，不会被\(a\)和\(b\)纠缠不清，设\(A=pa/(pa+pb)\)，\(B=pb/(pa+pb)\)，则有：\[f

今天早上打开电脑，更新了日常工作的github仓库，然后就是习惯性地执行了"npminstall"，发现报了下面这个错误：Error:error:0308010C:digitalenveloperoutines::unsupported 顺便看了一下错误堆栈，发现是一个Node的内核文件抛出来的错误，我的第一反应这个错误应该是和Node的版本有关（前几天刚刚升级过Node），所以理所当然地降低Node的版本应该可以解决这个问题。或者使用nvm（Windows平台上也可以使用nvm-windows）安装多个不同的Node版本。 除了切换Node的版本来解决这个问题外，其实还可以尝试启用l
