Valid Anagram Explained with Simple Logic

Introduction String problems are very common in programming, and one of the most basic yet important problems is checking whether two strings are anagrams. This problem helps build a strong understanding of character frequency and hashing. Problem Statement Given two strings s and t , return true if t is an anagram of s , and false otherwise. What is an Anagram? Two strings are anagrams if: They contain the same characters With the same frequency But possibly in a different order Example 1: Input: s = " anagram " t = " nagaram " Output: True Example 2: Input: s = " rat " t = " car " Output: False Approach 1: Sorting Method Sort both strings Compare the sorted results Python Implementation def is_anagram ( s , t ): return sorted ( s ) == sorted ( t ) # Example usage print ( is_anagram ( " anagram " , " nagaram " )) Approach 2: Using Dictionary (Efficient) Count frequency of each character Compare frequencies Python Implementation def is_anagram ( s , t ): if len ( s ) != len ( t ): retu
