Find the length of the longest substring without repeating characters in a given string s. Provide examples and edge cases to consider, such as empty strings or strings with only one character. Optimize for performance and time/space complexity, especially for large inputs.

Data Structures & AlgorithmsMedium

Given a string s, find the length of the longest substring without repeating characters. For example: Input: s = abcabcbb Output: 3 Explanation: The answer is abc, with the length of 3. Input: s = bbbbb Output: 1 Explanation: The answer is b, with the length of 1. Input: s = pwwkew Output: 3 Explanation: The answer is wke, with the length of 3. Notice that the answer must be a substring; pwke is a subsequence and not a substring. Input: s = Output: 0 Implement an algorithm in your chosen language to efficiently determine the length of the longest substring without repeating characters in the given input string. Consider the time and space complexity of your solution. Can you optimize your approach to achieve the best possible performance, especially for very large input strings? What are the edge cases to consider, such as empty strings or strings with only one character?
