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.
class Solution { public: bool isAnagram(string s, string t) { sort(s.begin(),s.end()); sort(t.begin(),t.end()); if(s==t) return true; return false; } };
