Solution: Car Pooling

Explore the car pooling problem by understanding how to simulate passenger pick-ups and drop-offs along a timeline. Learn to apply the difference array pattern to efficiently track passenger counts and verify if the car's seating capacity is exceeded during any part of the journey. This lesson helps you implement a solution that runs in linear time and constant space, deepening your grasp of interval management patterns for coding interviews.

Statement

You are given a car with a fixed number of seats, denoted by an integer capacity. The car only travels in one direction — eastward — and does not make any U-turns.

You are also provided with an array, trips, where each element trips[i] $= [\text{numPassengers}_i, \text{from}_i, \text{to}_i]$ represents a group of $\text{numPassengers}_i$ that must be picked up at location $\text{from}_i$ and dropped off at location $\text{to}_i$ ...
