Given a string s and a non-empty string p, find all the start indices of p's anagrams in s. Strings consists of lowercase English letters only and the length of both strings s and p will not be larger than 20,100. The order of output does not matter.…
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…
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.…

Write a method anagram(s,t) to decide if two strings are anagrams or not. 判断两个字符串里的字符是否相同,也就是是否能够通过改变字母顺序而变成相同的字符串. 如果是返回true,如果不是返回false. Clarification What is Anagram?- Two strings are anagram if they can be the same after change the order of chara…
Given an array of strings, group anagrams together. For example, given: ["eat", "tea", "tan", "ate", "nat", "bat"], Return: [ ["ate", "eat","tea"], ["nat",…
