Solution: Car Pooling

Explore how to determine if multiple trips fit within a car's capacity by simulating passenger changes along a timeline. Understand using difference arrays to monitor intervals and efficiently check capacity constraints.

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] =[numPassengersi,fromi,toi]= [\text{numPassengers}_i, \text{from}_i, \text{to}_i] ...
