How would you use containment to model the 'has-a' relationship between objects, with a focus on the benefits and alternatives to containment? Please provide examples using code snippets and real-world scenarios to back up your explanation, such as a smartphone containing a camera, screen, and battery. In addition, discuss when you might choose containment over inheritance. What are the real-world implications of containment in software design problems? Give at least two examples besides the device management system. Illustrate the class structure for Device, Smartphone, Camera, Screen, and Battery and how these classes would interact with each other. Explain the advantages of using containment and how it promotes code reusability, maintainability, and flexibility. What are the tradeoffs between containment and inheritance in this context, and when might you choose one over the other? The goal is to demonstrate an understanding of how containment works and its practical benefits in object-oriented design. Include clear explanations and code snippets to support your discussion, showcasing your ability to apply this concept to real-world problems effectively.

Data Structures & AlgorithmsHard

Let's explore the concept of containment. Imagine you're building a system for managing different types of electronic devices, such as smartphones, laptops, and tablets. Each device has specific properties and functionalities. You need a way to represent these devices and their relationships in a structured manner using object-oriented principles. Specifically, how would you use containment to model the 'has-a' relationship between a device and its components, such as a smartphone containing a camera, a screen, and a battery? Consider the following aspects in your design: Class Structure: How would you define the classes for Device, Smartphone, Camera, Screen, and Battery? Clearly demonstrate how these classes would interact with each other. Containment Implementation: Provide code snippets (in a language of your choice, such as Java, Python, or C++) to illustrate how you would implement containment to represent the 'has-a' relationship. Show how a Smartphone object would contain instances of Camera, Screen, and Battery objects. Benefits of Containment: Explain the advantages of using containment in this scenario. How does it promote code reusability, maintainability, and flexibility? Provide specific examples related to the device management system. Alternatives to Containment: Discuss other approaches to modeling relationships between objects, such as inheritance. What are the tradeoffs between containment and inheritance in this context? When might you choose one over the other? Real-World Implications: How does this concept of containment apply to other real-world scenarios or software design problems? Provide at least two examples beyond the device management system. For example, your Smartphone class might have member variables that are instances of the Camera, Screen, and Battery classes. This way, the Smartphone contains these components. Your explanation should cover how these components are created, accessed, and managed within the Smartphone class. The goal is to demonstrate a solid understanding of how containment works and its practical benefits in object-oriented design.

How would you design a URL shortening system like TinyURL?

System DesignMedium

Let's design a system for URL shortening, like TinyURL. Assume a large-scale service. Please consider the following aspects in your design: Functional Requirements: The system should generate shorter URLs (a.k.a. short links) given longer URLs. Users should be able to navigate to the original URL by entering the short link in their browser. The system should be highly available. Non-Functional Requirements: The system should have low latency for both URL shortening and redirection. Short links should be relatively short (e.g., 6-8 characters). The system should be able to handle a large number of URL shortening and redirection requests. Capacity Estimation: Assume 100 million URLs are shortened per day. Assume 1 billion URL redirections per day. Estimate storage requirements for 5 years. Design Considerations: How would you generate unique short links? What data structures and databases would you use to store the URL mappings? How would you handle collisions when generating short links? How would you optimize for low latency redirection? How would you scale the system to handle the expected traffic? Walk me through your design, explaining your choices and the trade-offs you considered. Provide diagrams where necessary to illustrate the architecture.
