The French author Georges Perec (1936–1982) once wrote a book, La disparition, without the letter 'e'. He was a member of the Oulipo group. A quote from the book: Tout avait Pair normal, mais tout s'affirmait faux. Tout avait Fair normal, d'abord, pu…

题意:给你两个字符串p和s,求出p在s中出现的次数. 显然,我们要先把模式串放到前面,之后主串放后面,中间隔开,这样就可以根据前缀数组的性质来求了. 我先想直接把p接到s前面,之后求Next数组对strlen(p)取余==0的就可以,之后WA.最后发现A AASSAAS的时候有bug,只有又想到在p和s中间加个不可能出现的字符'$'就可以了,接着就A了. #include <bits/stdc++.h> using namespace std; const int INF=0x3f3f3f3f…
