Given two strings s and t , write a function to determine if t is an anagram of s.

Example 1:

Input: s = "anagram", t = "nagaram"
Output: true

Example 2:

Input: s = "rat", t = "car"
Output: false

Note:
You may assume the string contains only lowercase alphabets.

Follow up:
What if the inputs contain unicode characters? How would you adapt your solution to such case?

class Solution {
    public boolean isAnagram(String s, String t) {
        if (s.length() != t.length()) return false;
        char[] arr1 = s.toCharArray();
        char[] arr2 = t.toCharArray();
        Arrays.sort(arr1);
        Arrays.sort(arr2);
        for (int i = 0; i < arr1.length; i++) {
            if(arr1[i]!=arr2[i]) return false;
        }
        return true;
    }
}
