Solution: Car Pooling

Explore how to determine if multiple trips can be completed in a car without exceeding its seating capacity. Learn to apply the intervals and difference array patterns to simulate passenger pick-up and drop-off points along a timeline, optimizing the approach for time and space efficiency.

We'll cover the following...

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 $\text{to}_i$ ...
