Design a class Car having parameterized constructor that takes two arguments as an input i.e noOfGear and color and a printCarInfo method that prints the CarInfo i.e noOfGear and color.

Design another class RaceCar having parameterized constructor has an additional attribute maxSpeed and printRaceCarInfo method that prints the RaceCarInfo i.e noOfGear, color and maxSpeed.

Note: You have to create an object of class RaceCar and call the printRaceCarInfo method.

You have to design a hit counter which supports the functionality of accepting a hit and returning the number of hits done in the last 5 minutes. Each call is made with a timestamp which is given in seconds.

It is possible to receive several hit arriving at the same time. All the calls are done in chronological order. The timestamp for a call is equal to or greater than the Timestamp for the call just before it. Timestamp at the start can be considered as 0.

For example:

The counter is hit at 'T'  = 1
The counter is hit at 'T' = 50
The getHit function at 'T' = 100 returns 2
The counter is hit at 'T' = 250
The getHit function at 'T' = 100 returns 2

You have been given a linked list of integers. Your task is to write a function that deletes a node from a given position, 'POS'.

Note :

Assume that the Indexing for the linked list always starts from 0.

If the position is greater than or equal to the length of the linked list, you should return the same linked list without any change.

Illustration :

The following images depict how the deletion has been performed.
