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…
1. 把string变为char数组 2. 排序Arrays.sort() public class Solution { /** * @param s: The first string * @param b: The second string * @return true or false */ public boolean anagram(String s, String t) { if(s == null || t == null) return false; if(s.length(…
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…
