Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 这道题让我们找出给定字符串集中所有的错位词,所谓的错位词就是两个字符串中字母出现的次数都一样,只是位置不同,比如abc,bac, cba等它们就互为错位词,那么我们如何判断两者是否是错位词呢,我们发现如果把错位词的字符顺序重新排列,那么会得到相同的结果,所以重新排序是判…

原题地址:https://oj.leetcode.com/problems/anagrams/ 题意: Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 解题思路:anagram的意思是:abc,bac,acb就是anagram.即同一段字符串的字母的不同排序.将这些都找出来.这里使用了哈希表,即Python中的dic…

题目 Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 思路 1. 使用数组模拟哈希表, 数组下标0-25分别代表字符'a'-'z', a[0] 代表 'a' 在单词中出现的次数 2. 排序, 只有相邻的单词才有可能是相同的 3. 这么慢的方法没想到 176ms 就能通过 总结 1. word 起初没有对 char 数…

Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 原题链接:https://oj.leetcode.com/problems/anagrams/ 易位构词游戏的英文词汇是 anagram,这个词来源于有"反向"或"再次"的含义的希腊语字根ana-和有"书写"."…

Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 题目的意思是:给出一组字符串,按组返回拥有相同变位词的字符串 解题思路是: 对单词中得字母排序,如果排序后的单词是一样的,那么我们可以判定这两个单词有相同的变位词. 首先,求出每个单词的变位词,以变位词作为键插入哈希表中,值为一个链表. 然后,把该单词附在这个链表末端.…

Anagrams Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 我的解题思路是这种:1.事实上所谓的anagrams就是字母同样就ok了 2.把每一个数组里面的数字以字典序进行又一次排序形成fingerprint 3.推断排序过得串是否在hashmap里面,假设在里面就加一,说明这个fingerprint 有了 有…

AnagramsGiven an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 思路: 建Hashtable,用排序过的string作为key,它的anagram作为ArrayList 这道题之前用暴力写的O(N^2)的TLE了,改用Hashtable来写题目的意思是给一个String数组,找出其中由相同字母组成的单词.例如:S =…

Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 题意:anagrams的意思是回文构词法.回文构词法有一个特点:单词里的字母的种类和数目没有改变,只是改变了字母的排列顺序.如: Input: ["tea","and","ate","eat",&qu…

[LeetCode] Anagrams   Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case.   思路:   Anagrams指几个string有相同的字符,但不同的字符顺序.所以一个有效的检查方法是:当两个string排序以后相同,则它们是anagrams.可以使用一个hash table,string s的key是…
