上一次打BC是Round4,被感人的PP坑出阴影了,导致好长一段时间没打

开了A后,感觉不难,于是就写掉了,太久没打CF手速越来越慢了。。

开了B后,感觉不难,于是写啊写,快写完时发现没看到最长,深感到自己视力堪忧

于是重写了,写啊写,写完了。发现过不了第二个样例,去问了下出题人,发现题目看错了。。还以为是合法的前提下最长

深感到自己语文堪忧,于是重写了,写啊写,写完了,于是就过pp了

开了C后,满满一种神题既视感,想了好久才发现只跟最近60个有关,深感到自己智力堪忧,于是写啊写写完了

看了下D,发现是计数问题,于是就弃聊了。

cha人时发现B没开LL能过pp,于是开始cha,大概发现了5个结果只得手3个

cha的过程中发现自己特判了L=1和R=n的情况,于是愉快地FST了

然后发现自己C用了1<<64,于是C也FST啦

于是就滚粗啦
