Difficulty: Easy Problem You are given an array A of strings. Two strings S and T are special-equivalent if after any number of moves, S == T. A move consists of choosing two indices i and j with i % 2 == j % 2, and swapping S[i] with S[j]. Now, a gr…

Question 893. Groups of Special-Equivalent Strings Solution 题目大意: AB两个字符串相等的条件是:A中偶数位出现的字符与B中偶数位出现的字符相同且奇数位出现的字符也相同 按上述判定相等字符串的规则求去重后字符串的个数 思路: strHash函数,传一个字符串,返回该字符串的奇数位字符和偶数位字符出现的在字母表中的分布 构造一个set来存储每个字符串的strHash后的结果 Java实现: public int numSpecialEq…

Equivalent Strings 题目链接:http://acm.hust.edu.cn/vjudge/contest/view.action?cid=84562#problem/E 题意: 给出两个字符串,确定是否相等.一个字符串分割成相同大小的两半a1和a2,另一个字符串分割成相同大小的成两半b1和b2. 以下是正确的:a1相当于b1 ,a2相当于b2a1相当于b2 ,a2相当于b1 Sample Input Input aabaabaa Output YES Input aabbaba…

Equivalent Strings Problem's Link: http://codeforces.com/contest/559/problem/B Mean: 给定两个等长串s1,s2,判断是否等价. 等价的含义为: 若长度为奇数,则必须是相同串. 若长度是偶数,则将两串都均分成长度为原串一半的两个子串l1,r1和l2,r2,其中l1和l2等价且r1和r2等价,或者l1和r2等价且l2和r1等价. analyse: 直接按照题意模拟写个递归分治就行.比赛的时候总觉得这样暴力写会TLE,…
