Solution: Valid Anagram
Understand how to verify if one string is an anagram of another by efficiently tracking character counts. This lesson explores both naive and optimized approaches to solving valid anagram problems, guiding you to implement a linear time solution using a hash map for frequency counting and learn the trade-offs in complexity.
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.
