Solution: Find All Anagrams in a String
Explore how to find all starting indexes of anagrams of a given string within another string by leveraging a sliding window approach and frequency hash maps. Understand how to compare character counts instead of substrings directly to detect anagrams efficiently, and learn how to handle edge cases and optimize time and space complexity.

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”.
