leetcode-242. Valid Anagram

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.

解法一，暴力解决

class Solution {
public:
    bool isAnagram(string s, string t) {
        if(s.size() != t.size()) return false;

        sort(s.begin(), s.end());
        sort(t.begin(), t.end());

        for(int i =0; i < s.size(); ++i){
            if(s[i] != t[i]) return false;
        }
        return true;
    }
};
