Find the contiguous subarray with the largest sum.

Data Structures & AlgorithmsMedium

You are given an array of integers. Write a function to find the contiguous subarray with the largest sum and return that sum. For example: Given the array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the contiguous subarray [4, -1, 2, 1] has the largest sum = 6. Given the array [1, 2, 3, 4, 5], the contiguous subarray [1, 2, 3, 4, 5] has the largest sum = 15. Given the array [-1, -2, -3], the contiguous subarray [-1] has the largest sum = -1. Your function should be efficient and handle arrays with both positive and negative numbers. Explain the time complexity of your solution. Can you implement this using dynamic programming? Are there other approaches? Discuss the tradeoffs of the various potential solutions.

How would you scale a social media platform to handle millions of users and real-time updates?

System DesignMedium

Let's explore scalability with a practical scenario. Imagine you're building a social media platform like Twitter, which needs to support millions of users who are constantly posting, liking, and re-sharing content. Consider these factors: Data Volume: Users generate terabytes of data daily. Read/Write Ratio: The platform experiences a high read-to-write ratio (many more reads than writes). Real-time Updates: Users expect to see new content and updates in real-time. Given these requirements, discuss the following: What are the key scalability challenges you anticipate? How would you approach scaling the platform's architecture to handle the increasing load, including database design, caching strategies, and load balancing? Describe specific technologies and techniques you might use to address each challenge. What are the trade-offs associated with different scaling approaches, and how would you evaluate the effectiveness of your scaling efforts?
