假如两个区间的26的字母出现的位置集合分别是 A1,B1,A2,B2,....., 我们再能找到一个排列p[] 使得 A[i] = B[p[i]] ,那么就可以成功映射了. 显然集合可以直接hash,排序一下hash值就可以判断是否匹配了.... 虽然不知道为什么要卡19260817,但反正我是坚决不写双hash的,最后随便换了一个大模数(甚至都不是质数2333)然后就过了... Discription You are given a string s of length n consistin…

Codeforces Educational Codeforces Round 44 (Rated for Div. 2) F. Isomorphic Strings 题目连接: http://codeforces.com/contest/985/problem/F Description You are given a string s of length n consisting of lowercase English letters. For two given strings s an…

F - Isomorphic Strings 思路:字符串hash 对于每一个字母单独hash 对于一段区间,求出每个字母的hash值,然后排序,如果能匹配上,就说明在这段区间存在字母间的一一映射 代码: #include<bits/stdc++.h> using namespace std; #define fi first #define se second #define pi acos(-1.0) #define LL long long //#define mp make_pair…

F - Isomorphic Strings 题目大意:给你一个长度为n 由小写字母组成的字符串,有m个询问, 每个询问给你两个区间, 问你xi,yi能不能形成映射关系. 思路:这个题意好难懂啊...  字符串哈希, 将26个字符分开来hash, 那么check就变成啦, 区间内对应的26个字符的hash值是否一致. 即如果 a -> b  那么区间1内a的hash值等于区间2内b的hash值. #include<bits/stdc++.h> #define LL long long #…

Question 205. Isomorphic Strings Solution 题目大意:判断两个字符串是否具有相同的结构 思路:构造一个map,存储每个字符的差,遍历字符串,判断两个两个字符串中相同位置字符的差是否相同 Java实现: public boolean isIsomorphic(String s, String t) { Map<String, Integer> map = new HashMap<>(); for (int i=0; i<s.length(…

题面戳我 Solution 我们按照每个字母出现的位置进行\(hash\),比如我们记录\(a\)的位置:我们就可以把位置表示为\(0101000111\)这种形式,然后进行字符串\(hash\) 每次查询时,我们就把两个子串的每个字母的\(hash\)值,取出来,判断能否一一对应即可 为啥我的常数那么大,2700ms Code //It is coded by ning_mew on 7.23 #include<bits/stdc++.h> #define LL long long usin…
