Valid Anagram

Description

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) {

		int A[26] = { 0 }, B[26] = { 0 };

		size_t i, n = s.length(), m = t.length();

		if (n != m) return false;

		for (i = 0; i < n; i++) A[s[i] - 'a']++;

		for (i = 0; i < m; i++) B[t[i] - 'a']++;

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

			if (A[i] != B[i]) return false;

		}

		return true;

	}

};
