242. Valid Anagram Add to List

Posted 2020-08-25 Hutonm

Given two strings s and t, write a function to determine if t is an anagram of s.

For example,
s = "anagram", t = "nagaram", return true.
s = "rat", t = "car", return false.

Note:
You may assume the string contains only lowercase alphabets.

//排个序比较一下

//或者用数组记录每个单词出现的次数

//在这我用的是第一种方法，比较快。

 6         else{
 7             sort(s.begin(),s.end());
 8             sort(t.begin(),t.end());
