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): return False count = {} # Count characters i
