// Imagine you are working on a city planning project, and you need to optimise the placement of street lamps to illuminate as many street segments as possible. Each point in the array represents the location of a building or a potential street lamp on the X-Y plane. To minimise costs and energy consumption, you want to find the maximum number of street lamps that can be aligned in a straight line to cover multiple buildings or street segments.
