Given an array of integers, write a function to find the contiguous subarray with the largest sum. Return the sum of that subarray. For example: Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6 Explanation: The contiguous subarray [4, -1, 2, 1] has the largest sum = 6. Constraints: The array can contain positive, negative, and zero integers. The subarray must be contiguous (elements must be adjacent). If all numbers are negative, the function should return the largest negative number (or 0 if the array is empty). Your function should be efficient and handle arrays of various sizes. Consider edge cases such as an empty array or an array with only one element. What is the time and space complexity of your solution?

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?
