Solution: Find All Anagrams in a String
Explore how to identify all anagrams of a given string within another string by using a sliding window technique combined with hash maps to track character counts. Understand how to efficiently detect anagrams without direct substring comparison, evaluate time and space complexity, and apply these concepts to solve frequency-related coding problems.

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”.

-
a.length,b.length
