Using stack , basically the idea is if the backcar takes less time to reach destination than front car then it must mean that the become a fleet and remove the backcar since obviously if backcar crosses front car it has higher speed than front car but we need the speed to be equal to minimum speed when it becomes a fleet so thats why we remove backcar and not front car and then in the end return length of stack
