Problem: Valid Anagram

Explore how to verify if two strings are anagrams by counting character frequencies using a hash map. This lesson guides you through implementing an efficient Go solution that handles lowercase English letters and discusses adapting for Unicode characters while analyzing time and space complexity.

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 ...
