Problem: Permutation in String
Explore how to determine if one string contains any permutation of another as a substring by applying a sliding window technique with character frequency counting. Understand the optimization of matches tracking for constant time updates and learn to implement this algorithm efficiently in Python for string-related problem solving.

Statement
Given two strings s1 and s2, determine whether s2 contains any permutation of s1 as a substring. Return true if such a substring exists, and false otherwise.
Note: A permutation of a string is any rearrangement of its characters. You need to check whether any contiguous substring of
s2is an anagram ofs1.
Constraints:
s1.length,s2.length...
