Solution: Find All Anagrams in a String
Explore how to identify all starting positions of anagrams of one string within another by applying sliding window and character frequency tracking techniques. Understand how to efficiently compare character counts using hash maps to detect anagrams without direct substring comparisons. This lesson guides you through implementing an optimal solution with clear time and space complexity considerations.
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
