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.

class Solution {

public:

bool isAnagram(string s, string t) {

vector<int> count(26, 0);

for(int i = 0; i < s.size(); i ++)

count[s[i]-‘a‘] ++;

for(int i = 0; i < t.size(); i ++)

count[t[i]-‘a‘] --;

for(int i = 0; i < 26; i ++)

if(count[i] != 0)

return false;

return true;

}

};

 

 

class Solution {

public:

bool isAnagram(string s, string t) {

sort(s.begin(), s.end());

sort(t.begin(), t.end());

return s == t;

}

};
