Find All Anagrams in a String
Explore how to identify all start indexes of anagrams of one string within another by using frequency tracking methods. Learn to understand the problem requirements, develop an approach to track character counts, and implement a solution that efficiently detects anagrams in JavaScript. This lesson helps you apply pattern recognition for common string problems relevant in coding interviews.
We'll cover the following...
Statement
Given two strings, a and b, return an array of all the start indexes of anagrams of b in a. We may return the answer in any order.
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. For example, “act” is the anagram of “cat”, and “flow” is the anagram of “wolf”.
