两个字符串是变位词

class Solution {
public:
    /**
     * @param s: The first string
     * @param b: The second string
     * @return true or false
     */
    bool anagram(string s, string t) {
        // write your code here
        vector<char> vec1,vec2;
        for(int i = 0; i < s.size(); ++i)
            vec1.push_back(s[i]);
        for(int j =0; j < t.size(); ++j)
            vec2.push_back(t[j]);
        sort(vec1.begin(),vec1.end());
        sort(vec2.begin(),vec2.end());
        return vec1 == vec2;
    }
};
