Design and implement an LRU (Least Recently Used) Cache. It should support get and put operations in O(1) time complexity.

#Hash Map #Doubly Linked List #Data Structures
Software Engineer Coding medium

You are given a list of overlapping ride requests, where each request has a start time and end time. Write a function to merge all overlapping ride times and return the consolidated active driving periods.

Implement a Rate Limiter. Given a user ID and a timestamp, return true if the request should be allowed, and false if it exceeds the limit of N requests per M seconds.

#Sliding Window #Queues #Concurrency #Hash Map
Software Engineer Coding medium

Given a grid representing a city map where 0 is a valid road, 1 is a traffic jam (impassable), and a start and end coordinate, find the shortest path for an Uber driver to reach the destination.
