对于t, 同样将其遍历,对每个出现的字符计数减一。 如果s和t是anagram , 那么最后的charcount数组中所有字符的计数都应该是0, 否则就不是anagram。 [Code] 1: class Solution { 2: public: 3: boolisAnagram(string s, string t) { 4: vector<int>charcount(26,0); 5:for(int i =0;i< s.length(...
对字符排序,如果排序后相等则true。 1classSolution {2public:3boolisAnagram(strings,stringt) {4sort(s.begin(),s.end());5sort(t.begin(),t.end());6if(s==t)returntrue;7elsereturnfalse;8}9};
【leetcode】242. Valid Anagram problem 242. Valid Anagram 首先,要先弄清楚什么是anagram,anagram是指由颠倒字母顺序组成的单词。 解决方法一种是排序,一种是哈希表。 solution: class Solution { public: bool isAnagram(string s, string t) { if(s.length()!=t.length()) return false;...
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…
s= "anagram",t= "nagaram", return true. s= "rat",t= "car", return false. Note: You may assume the string contains only lowercase alphabets. [思路] sort 以后看是否相等 思路2: bitmap, 数字符个数是否相等. [CODE] public class Solution { ...
242. 有效的字母异位词 Valid Anagram LeetCodeCN 第242题链接 第一种方法:对两个字符串排序后对比 classSolution:defisAnagram(self,s:str,t:str)->bool:returnsorted(s)==sorted(t) 第二种方法:用哈希表对字符串内每个字符计数,最后比对哈希表,这里用dict实现 ...
s = "anagram", t = "nagaram", return true. s = "rat", t = "car", return false. Note: You may assume the string contains only lowercase alphabets. Follow up: What if the inputs contain unicode characters? How would you adapt your solution to such case?

leetcode(242) ——Valid Anagram 题目:ValidAnagram题目就是要求判断两个字符串是否是由相同字符组成,但是字符的排序是不同的,也就是相同字母异序词。 解答题目: 代码: 运行截图: LeetCode-242. 有效的字母异位词、409. 最长回文串、205. 同构字符串 ...
Can you solve this real interview question? Valid Anagram - Given two strings s and t, return true if t is an anagram of s, and false otherwise. Example 1: Input: s = "anagram", t = "nagaram" Output: true Example 2: Input: s = "rat", t = "car" O
