Find All Anagrams in a String - Sliding Window Technique - LeetCode 438

Solving the LeetCode problem 438 Find All Anagrams in a String using the Sliding Window Technique.

In this video, we will be solving LeetCode problem 438, which is to find all anagrams of a given string P in another string S. An anagram is a word or phrase formed by rearranging the letters of a different word or phrase. We will be using the sliding window technique to solve this problem efficiently.

The video starts with a brief explanation of what anagrams are and the problem statement. Then, it dives into the solution using the sliding window technique. The solution works by creating a map representation of the string P and then iterating through the string S, checking if each substring of length equal to the length of P is an anagram of P using the map representation. The sliding window technique optimizes this process by only updating the map representation for the characters that enter and leave the window, instead of recreating the map representation for each substring.
