Why is 3.14 called pi? As pi is an irrational number, the digits after its decimal point are never-ending. In order to use the value of pi in day-to-day calculations, various approximations of the value of pi are used. One of these approximations is the value 3.14. Thus, 3.14 is of...
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。
There is more of me To forget than you can remember —Emma Beauxis-Aussalet 2022年我们根据 π 的数学原理创作了一张专辑,这张专辑名为《three one four: a number of digits》,从音乐上诠释了以π(314…)开头和以π(264)结尾的数字。 这张专辑是为20世纪古典音乐风格的钢琴独奏配乐——每首曲子都有...
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 you take, for example, the epic novel "War...
In fact, the number for pi is much longer. Pi is called an trrational number(无理数) because the digits (数位) after the decimal point(小数) never end or repeat.In 2015, a young man from Indi a named Rajveer Meen a set a world record by memorizing 70,000 digits of pi. But pi ...
【CF585F】Digits of Number Pi(AC自动机上数位DP),给定一个长为$n$的字符串$s$和两个长为$d$的字符串$l,r$。问有多少长为$d$的在$[l,r]$内的字符串,满足存在长度至少为$\lfloor\fracd2\rfloor$的子串是$s$的子串。
如果我们把ss每个长度为⌊d2⌋⌊d2⌋的子串都取出来建一个ACAC自动机,那么我们就是要求有多少个[l,r][l,r]内的字符串能匹配到至少一个模式串。于是就设fx,rt,0/1,0/1fx,rt,0/1,0/1表示做到第xx个字符、对应ACAC自动机上编号为rtrt的节点、是否完成过匹配、是否卡到数字上界的方案数。
They try to remember as many digits(数字) of pi as they can. It shows their memory skills. In Germany, the celebration of Pi Day pays more attention to creativity.4 A student even built a 3- D building with Lego about pi. She used different colored blocks to show each digit of pi,...

The Guinness World Record for reciting(背诵) the most digits of Pi is held by Lyu Chao of China,who successfully recited Pi out to nearly 67,890 decimal places.Above all, Pi Day is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with fun games ...
