Longest Substring Without Repeating Characters — LeetCode #3 (Medium)
The article discusses the problem of finding the length of the longest substring without repeating characters. It explains the sliding window technique used to solve this problem efficiently. The author provides a Python code implementation and a detailed walkthrough of the algorithm.
- ▪The problem requires returning the length of the longest substring that contains no duplicate characters.
- ▪The sliding window technique involves using two pointers to manage the current substring and a set to track characters.
- ▪The provided Python code initializes a set and uses a loop to iterate through the string while adjusting the pointers as needed.
