Solution: Find All Anagrams in a String
Explore how to identify all starting indices of anagrams of a given string within another string by using sliding window and hash map character counts. Understand the approach to compare character frequencies instead of direct substring matching, and how to implement this efficiently in JavaScript. This lesson helps you grasp key concepts for tracking elements in data and applying them to solve common coding interview problems.
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”.
Constraints:
-
a.length,b.length
