Problem

PayPal may compare normalized reference strings when validating a payment request. Given two strings, determine whether they are anagrams, meaning one can be formed by rearranging all characters of the other.

The comparison is case-sensitive, and every character must be matched exactly. For this problem, inputs contain only lowercase English letters. Repeated characters must occur the same number of times.

Formal Specification

Implement is_anagram(s, t):

Input: two strings s and t containing zero or more lowercase English letters.
Output: return True if s and t are anagrams, otherwise return False.
The function must not modify either input string.

Constraints

0 <= len(s), len(t) <= 5 * 10^4
s and t contain only lowercase English letters
The input strings must not be modified
