0242: Valid Anagram

Problem Statement

Given two strings s and t, return true if t is an anagram of s, and false otherwise.

Example 1:

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

Output: true

Example 2:

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

Output: false

Constraints:

  • 1 <= s.length, t.length <= 5 * 104
  • s and t consist of lowercase English letters.

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

Code Solution

from collections import Counter

class Solution:
    def isAnagram(self, s, t):
        if len(s) != len(t):
            return False
        return Counter(s) == Counter(t)
