Valid Anagram
Understand how to verify if one string is an anagram of another by effectively tracking character counts. Learn the key constraints and apply coding techniques to implement solutions in JavaScript, strengthening your problem-solving skills for coding interviews.
We'll cover the following...
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 -
str1andstr2consist of only lowercase English letters.
