题目大意 给出两个\(01\)序列\(A\)和\(B\) 哈明距离定义为两个长度相同的序列中,有多少个对应位置上的数字不一样 "00111" 和 "10101"的距离为2 \(Q\)次询问,每次询问给出\(p_1,p_2,len\) 求\(a{p_1},a{p_1+1}...a_{p_1+len-1}\) 和 \(b_{p_1},b_{p_1+1}...b_{p_1+len-1}\)两个子串的哈明距离 注意:本题中的序列是从\(0\)开始编号的:\(a_0,a_1,…

Description 给出两个01序列\(A\)和\(B\) 要求回答\(q\)个询问每次询问\(A\)和\(B\)中两个长度为\(len\)的子串的哈明距离 ​ 哈明距离的值即有多少个位置不相等 ​ \(1 \le |A|,|B| \le 2*10^5\) ​ \(1 \le q \le 4*10^5\) ​ 保证输入合法,序列下标从0开始 Solution ​ 大暴力分块,记录一下思想 ​ 题解做法比较繁琐 ​ 先求出每一个位置开始长度为32的序列状态,压进一个unsigned int ​…

Increase the Constraints 定义两个等长的01字符串的汉明距离为它们字符不同的对应位置的个数. 给你两个01串S,T,现在有q个询问,每次指定S,T中两个定长的子串询问它们的汉明距离. 1≤|S|,|T|≤200000,1≤q≤400000 cz_xuyixuan的题解 字符不同=长度-字符相同.考虑到两个字符串的匹配问题可以用FFT处理,于是往FFT方面考虑. 分块FFT,令分块大小为B,进行O(\(\frac{n}{B}\))次FFT,处理出O(\(\frac{n}{B…
