Solution: Valid Anagram
Explore efficient methods to verify whether one string is an anagram of another. Understand a naive sorting technique and then master an optimized solution using frequency counting, which leverages hash maps for linear time and constant space complexity. This lesson guides you in applying these strategies to solve anagram problems effectively.
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.
