Anagram Problem Solution | Dataford Interview Questions

Beaconfiresolution needs to validate whether two strings represent the same character sequence in different orders. Given two strings s and t, determine whether t is an anagram of s.

Two strings are anagrams when they contain exactly the same characters with the same frequencies. Character order does not matter, but every occurrence must be matched. Return True if the strings are anagrams and False otherwise.

Input: Two strings, s and t.
Output: A Boolean value. Return True when s and t contain identical character frequencies; otherwise return False.
