Solution: Valid Anagram
Explore how to verify if two strings are anagrams by tracking character counts. Understand the naive sorting method and an optimized frequency counting approach that runs in linear time and uses constant space. This lesson guides you through the logic and implementation details to efficiently solve the valid anagram problem using hash maps and character counting techniques.
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.
