Question
A shuttle with a fixed passenger capacity drives strictly east along a number line, never reversing. You are given trips, each [numPassengers, start, end], meaning that many passengers board at location start and alight at location end (they occupy the vehicle on [start, end)). Return True if it is possible to serve every trip without ever exceeding capacity, otherwise False.
car_pooling(trips: list[list[int]], capacity: int) → bool[[[2,1,5],[3,3,7]],4]outfalseState your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
