Given two strings s and t , Write a function to determine t Whether it is s Letter heteronym of .

Be careful ： if s and t Each character in the has the same number of occurrences , said s and t They are mutually alphabetic words .

#  Method 3- Direct initialization counter 

class Solution:

    def isAnagram(self, s: str, t: str) -> bool:

        if len(s) != len(t):

            return False

        return Counter(s) == Counter(t)

# Initialize counter 
class Solution:
    def isAnagram(self,s:str,t:str) -> bool:
        if len(s) != len(t):
            return False
        return Counter(s) == Counter(t)
