设状态 f(pos,cur,lenth,lim,flag)f(pos,cur,lenth,lim,flag),表示数位的位数,在 SAMSAM 上的节点,匹配的长度,是否有最高位限制,是否已经满足要求。 在dfsdfs 转移时,若当前节点能接着匹配枚举到的字符,就直接转移,若不能,则在 ParentParent 树上向上跳,直到能接着匹配,转移过程中判断是否满足条件即可。
Codeforces 585F. Digits of Number Pi 题解 题目链接:F. Digits of Number Pi题目大意:洛谷题解:观察到n,dn,d都很小,所以我们可以把ss中所有长度为⌊d2⌋⌊d2⌋的子串全部拿出来建一个 AC 自动机,然后将限制差分一下改成小于等于一个数的有多少个,然后直接跑一遍非常暴力的数位 DP 即可。
\(AC\)自动机上数位\(DP\) 如果我们把\(s\)每个长度为\(\lfloor\frac d2\rfloor\)的子串都取出来建一个\(AC\)自动机,那么我们就是要求有多少个\([l,r]\)内的字符串能匹配到至少一个模式串。 于是就设\(f_{x,rt,0/1,0/1}\)表示做到第\(x\)个字符、对应\(AC\)自动机上编号为\(rt\)...

#P585F. Digits of Number Pi Description Vasily has recently learned about the amazing properties of numberπ. In one of the articles it has been hypothesized that, whatever the sequence of numbers we have, in some position, this sequence is found among the digits of numberπ. Thus, if ...
On Aug 16,Swiss research said they broke a new record.Using a supercomputer,they calculated (计算) pi to 62.8 trillion(万亿) digits.The team at University of Applied Sciences in Graubunden,Switzerland took 108 days and nine hours to do this!

CF585F Digits of Number Pi 题目 把\(s\)串所有长度为\(\lfloor \frac{d}{2}\rfloor\)的子串插入一个ACAM中,之后数位dp就好了,状态是\(dp_{i,j,0/1}\)第\(i\)位,在ACAM上的节点\(j\),不卡/卡上界;正难则反一下,统计所有不能被表示即没有经过结束标记的路径即可...

Pi primes I was reading a recentblog postby Evelyn Lamb where she mentioned in passing that 314159 is a prime number and that made me curious how many such primes there are. Let’s look at numbers formed from the digits of π to see which ones are prime....
