class Solution:
    def isAnagram(self, s: str, t: str) -> bool:
        l = len(s)
        if l != len(t):
            return False
        ar = [0 for _ in range(26)]
        for i in range(l):
            ar[ord(s[i])-ord('a')] += 1
            ar[ord(t[i])-ord('a')] -= 1
            
        for i in range(26):
            if ar[i]:
                return False
