Grokking the Coding Interview Patterns in Go

Solution: Car Pooling

Explore how to solve the car pooling problem by simulating passenger pick-ups and drop-offs using a difference array and timeline. Understand the merge intervals pattern to track capacity efficiently and ensure the car never exceeds its limit during trips. Learn to implement this approach with linear time complexity and constant space, enabling you to apply this method to similar interval-related coding interview problems.

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] ...
