Solution: Valid Anagram
Explore how to verify if two strings are anagrams by tracking character frequencies. This lesson guides you through both a sorting approach and an optimized linear time frequency counting method, helping you write efficient code with clear understanding of space and time complexity trade-offs.
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.
Constraints:
-
str1.length,str2.length -
str1andstr2...
