[LeetCode] 242. Valid Anagram Java 题目: Given two strings s and t, write a function to determine if t is an anagram of s. For example,s = "anagram", t = "nagaram", return true.s = "rat", t = "car", return false.
此解法是将两字符串s、t转换为字符数组,然后将数组排序,最后比较两数组的元素是否相等,这里借助了工具类Arrays。 此解法的时间复杂度是O(nlog(n)),空间复杂度是O(n)。 publicbooleanisAnagram(Strings,Stringt) {if(s ==null|| t ==null|| s.length() != t.length()) {returnfalse; } char[] ch ...
解法二:哈希表,判断两个字符串相同字母的个数是否相等 1classSolution {2public:3boolisAnagram(strings,stringt) {4intlen_s = s.length(), len_t = t.length(), i, ns[26] = {0};5//vector<int> ns(26, 0);67for(i =0; i < len_s; i++)8ns[s[i] -'a']++;9for(i =0; i ...

Given two strings s and t, return true if t is an anagram of s, and false otherwise.An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using al…
LeetCode.jpg 有效的字母异位词 给定两个字符串 s 和 t ,编写一个函数来判断 t 是否是 s 的一个字母异位词。 示例1: 输入: s = "anagram", t = "nagaram" 输出: true 示例2: 输入: s = "rat", t = "car" 输出: false 说明: 你可以假设字符串只包含小写字母。
