Code Design – Rate Limiter. Here is the exact question I received. Problem Title: Rate Limiter Problem Description: Imagine we are building an application that is used by many different customers. We want to avoid one customer being able to overload the system by sending too many requests, so we enforce a per-customer rate limit. The rate limit is defined as: “Each customer can make X requests per Y seconds” Assuming that customer ID is extracted somehow from the request, implement the following function. // Perform rate limiting logic for provided customer ID. Return true if the // request is allowed, and false if it is not. boolean rateLimit(int customerId)
