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?

Let's design the LinkedIn feed. Consider the user experience, key features, scalability, and personalization aspects. For instance, how would you prioritize content from connections versus suggested content? How would you handle different content types like text, images, videos, and articles? How do you design a system to ensure that the feed remains responsive even with millions of active users? How would you personalize the feed to show users content they are most likely interested in, and what data would you use to achieve this personalization? Finally, how would you prevent the spread of misinformation or harmful content within the feed?

Okay, let's explore your interest in LinkedIn. To help me understand your motivations, could you elaborate on why you are particularly interested in working at LinkedIn? I'm looking for specific reasons beyond just wanting a job. For instance, are you drawn to LinkedIn's mission of connecting professionals? Perhaps you're excited about the scale of the platform and the impact you could have on millions of users? Or maybe you admire the company's culture and values, such as its emphasis on transformation, integrity, collaboration, and results. It would be helpful to hear about specific projects or initiatives at LinkedIn that resonate with you. Have you been following LinkedIn's work in AI, education, or small business support? Are there any particular LinkedIn products that you find innovative or impactful? Are you inspired by the work of a specific team? Furthermore, how do you see your skills and experience aligning with LinkedIn's goals? What unique contributions do you believe you can make to the company, and how would working at LinkedIn help you grow professionally? I'm interested in understanding how your personal values align with LinkedIn's core principles, and why you believe this is the right place for you to advance your career.
