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 group of special-equivalent…
Given two words word1 and word2, find the minimum number of steps required to make word1 and word2 the same, where in each step you can delete one character in either string. Example 1: Input: "sea", "eat" Output: 2 Explanation: You ne…

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…
