Solution: Valid Anagram
Explore how to verify if two strings are anagrams by comparing their character frequencies. Learn an optimized algorithm that uses a hash map for linear time complexity and constant space, improving on naive sorting methods. This lesson helps you implement an efficient solution for frequency-related string problems.
Statement
Given two strings, str1 and str2, check whether str2 is an anagram of str1.
An anagram is a word or phrase created by rearranging the letters of another word or phrase while utilizing each of the original letters exactly once.
