Solution: Valid Anagram
Explore how to verify if two strings are anagrams by tracking character frequencies efficiently. This lesson helps you understand and implement a linear time, constant space solution that counts characters in both strings to confirm their equivalence without sorting.
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.
