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:首先要理解,什么是anagrams,ie.“tea”.“tae”.“aet”,然后就十分好做了,new一个hashmap,使用一个排过序的String作为key,重复了就往里面添加元素,这里出现一个小插曲,就是排序的时候不要用PriorityQueue,因为P…

题目要求:Anagrams Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 分析: 参考网址:http://www.cnblogs.com/easonliu/p/3643595.html 代码如下: class Solution { public: vector<string> anagrams(vector<…

Anagrams Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case.     Anagrams:即字母个数和字母都相同,但是字母顺序不相同的词   e.g. "tea","and","ate","eat","dan".   retu…

Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. anagrams 的意思是两个词用相同的字母组成  比如 “dog" "god" 思路: 把单词排序 如 dog 按字母排序变为 dgo 用unordered_map<string, int> 记录排序后序列第一次出现时,字符串在输入st…

原题地址 Anagram:变位词.两个单词是变位词关系的条件是:组成单词的字符相同,只是顺序不同 第一次看这道题看了半天没明白要干嘛,丫就不能给个样例输入输出么..后来还是看网上其他人的总结知道是怎么回事. 通常的做法是:把字符串内的字符排序,这样,凡是变位词都会变成相同的单词.用map记录这样的单词出现了几个,如果超过1个,则加入结果集中. 代码: vector<string> anagrams(vector<string> &strs) { vector<stri…

Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 他的意思就是回文构词法,即单词里的字母的种类和数目没有改变,仅仅是改变了字母的排列顺序. input= ["abc", "bca", "bac", "bbb", "bbca", &…

Given an array of strings, return all groups of strings that are anagrams. Note: All inputs will be in lower-case. 题解: 判断字符串是否为回文构词法生成的.找出所有由同一回文构词法生成的字符串对. 使用map用于散列. 将strs中的字符串strs[i],在串内进行字典排序,生成key,原始s[i]不变. 将该字符串s[i]映射到key所对应位置.map[key].push_bac…

回文构词法,将字母顺序打乱.可将字母重新排序,若它们相等,则属于同一组anagrams. 可通过hashmap来做,将排序后的字母作为key.注意后面取hashmap值时的做法. vector<string> anagrams(vector<string> &strs) { unordered_map<string, vector<string>> group; for (const auto &s : strs) { string key…

11.2 编写一个方法,对字符串数组进行排序,将所有变位词1排在相邻的位置. 类似leetcode:Anagrams 解法: 变位词:由变换某个词或短语的字母顺序构成的新的词或短语.例如,“triangle”是“integral”的变位词. 此题有个要求,对数组中的字符串进行分组,将变位词排在一起.注意,除此之外,并没有要求这些词按特定顺序排列. 做法之一就是套用一种标准排序算法,比如归并排序或快速排序,并修改比较器.这个比较器用来指示两个字符串互为变位词就是相等的. 检查两个词是否为变位词,最…

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…
