Problem: Valid Anagram

Understand how to verify if two strings are valid anagrams by comparing their character counts using a dictionary. Learn to implement a linear time Python solution that efficiently handles lowercase English letters and adapt it for Unicode characters.

Statement

Given two strings s and t, determine whether t is an anagram of s. Return true if it is, and false otherwise.

An anagram is a word formed by rearranging all the letters of another word, using every letter exactly once.

Note: What if the inputs contain Unicode characters? How would you adapt your solution for that case?

Constraints:

  • 11 \leq s.length, t.length 5×104\leq 5 \times 10^4 ...
