Problem: Minimum Window Substring
Explore how to solve the minimum window substring problem by applying the sliding window technique with two pointers. Understand character frequency tracking and optimizations that yield an O(m+n) time complexity solution. This lesson helps you implement an efficient algorithm to identify the smallest substring containing all required characters, enhancing your skills in string manipulation and algorithm optimization.
We'll cover the following...
Statement
Given two strings s and t of lengths m and n, respectively, find the minimum window substring of s that contains every character in t, including duplicate characters. If no such substring exists, return an empty string "".
The test cases are generated such that the answer is always unique.
Note: Can you find an algorithm that runs in
time?
