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.

bool isAnagram(string s, string t) {
    sort(s.begin(), s.end());
    sort(t.begin(), t.end());
    return s == t;
}
