How would you sum the elements in an array of integers? What is the time complexity?

Data Structures & AlgorithmsMedium

Given an array of integers, write a function to calculate the sum of all the numbers in the array. For example, if the input array is [1, 2, 3, 4, 5], your function should return 15 (which is 1 + 2 + 3 + 4 + 5). Can you write an efficient function to do this, and what is the time complexity of your solution? As a follow-up, consider how you would handle extremely large arrays or arrays containing very large numbers to prevent overflow. Can you provide an example implementation in your preferred language?

Design a rate limiter for an API.

System DesignMedium

Let's design a rate limiter for an API. The rate limiter should: Limit the number of requests a user can make to an API within a given time window. Support different rate limits for different users or API endpoints. For example, a free tier user might be limited to 10 requests per minute, while a premium user can make 100 requests per minute. Similarly, some API endpoints might have lower rate limits than others due to resource constraints. Be highly performant to avoid adding significant latency to API requests. Be scalable to handle a large number of users and API requests. Be reliable and prevent accidental overloads that could cause service disruptions. Describe the architecture, algorithms, and data structures you would use to implement such a rate limiter. Consider the following: How would you store the rate limit counters for each user or endpoint? What algorithm would you use to determine whether a request should be allowed or throttled? How would you handle distributed rate limiting across multiple servers? How would you ensure the rate limiter is resilient to failures? As an example, imagine a scenario where a social media platform wants to prevent users from spamming their API with excessive requests to post updates. The platform has millions of users and thousands of API endpoints. Some users pay for premium access with higher request limits. How would you design a robust and efficient rate limiter to handle this scale and these varying requirements?
