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.
1 class Solution { 2 public: 3 bool isAnagram(string s, string t) { 4 sort(s.begin(),s.end()); 5 sort(t.begin(),t.end()); 6 return s==t; 7 8 } 9 };
