Solution: Find All Anagrams in a String
Understand how to identify all start positions of anagrams of a smaller string within a larger string by using a sliding window approach. This lesson teaches how to compare character counts with hash maps and manage window size to detect anagrams efficiently, with optimized 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”.
