# 242.有效字母异位词
- https://leetcode-cn.com/problems/valid-anagram
给定两个字符串 s 和 t ,编写一个函数来判断 t 是否是 s 的字母异位词。
注意:若s 和 t中每个字符出现的次数都相同,则称s 和 t互为字母异位词。
示例1:
输入: s = "anagram", t = "nagaram"
输出: true
示例 2:
输入: s = "rat", t = "car"
输出: false

class Solution: # 哈希法 def isAnagram(self, s: str, t: str) -> bool: if len(s) != len(t): return False records = [0] * 26 n = len(s) for i in range(n): records[ord(s[i]) - ord('a')] += 1 print(records) for i in range(n): records[ord(t[i]) - ord('a')] -= 1 for i in range(26): if records[i] != 0: return False return True if __name__ == "__main__": s = "handle" t = "" t1 = "and" t2 = "andhle" test = Solution() res = test.isAnagram(s, t) print(res) # False res = test.isAnagram(s, t1) print(res) # False res = test.isAnagram(s, t2) print(res) # True
