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.

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

Follow up:
What if the inputs contain unicode characters? How would you adapt your solution to such case?

=========

class {
public:
 bool isAnagram(string s, string t) {
        if(s.size() != t.size()) return false;
        sort(s.begin(),s.end());
        sort(t.begin(),t.end());
        int n = s.size();
        for(int i = 0;i<n;i++){
            if(s[i]!=t[i]) return false;
        }
        return true;
    }
};
