Solution: Valid Anagram
Explore methods to determine if two strings are anagrams by comparing character counts. Understand both the naive sort-based approach and an optimized frequency counting solution. Learn to implement the frequency counting method for linear time complexity and constant space, while handling string validation efficiently.
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.
