In this issue i will add solutions of Learning git branching of problems available on https://learngitbranching.js.org/

We want to store the information of different vehicles. Create a class named Vehicle with two data member named mileage and price. Create its two subclasses
*Car with data members to store ownership cost, warranty (by years), seating capacity and fuel type (diesel or petrol).
*Bike with data members to store the number of cylinders, number of gears, cooling type(air, liquid or oil), wheel type(alloys or spokes) and fuel tank size(in inches)
Make another two subclasses Audi and Ford of Car, each having a data member to store the model type. Next, make two subclasses Bajaj and TVS, each having a data member to store the make-type. Now, store and print the information of an Audi and a Ford car (i.e. model type, ownership cost, warranty, seating capacity, fuel type, mileage and price.) Do the same for a Bajaj and a TVS bike.

We want to calculate the total marks of each student of a class in Physics, Chemistry and Mathematics and the average marks of the class. The number of students in the class are entered by the user. Create a class named Marks with data members for roll number, name and marks. Create three other classes inheriting the Marks class, namely Physics, Chemistry and Mathematics, which are used to define marks in individual subject of each student. Roll number of each student will be generated automatically.

Create two classes named Mammals and MarineAnimals, Create another class named BlueWhale which inherits both the above classes.
Now, create a function in each of these classes which prints "I am mammal", "I am a marine animal" and "I belong to both the categories: Mammals as well as Marine Animals" respectively.
Now, create an object for each of the above class and try calling
1 - function of Mammals by the object of Mammal
2 - function of Marine Animal by the object of MarineAnimal
3 - function of BlueWhale by the object of BlueWhale
4 - function of each of its parent by the object of BlueWhale

We want to calculate the total marks of each student of a class
in Physics, Chemistry and Mathematics and the average marks of the
class. The number of students in the class are entered by the user.
Create a class named Marks with data members for roll number,
name and marks. Create three other classes inheriting the Marks
class, namely Physics, Chemistry and Mathematics, which are used to
define marks in individual subject of each student. Roll number of
each student will be generated automatically.

Coding Problem
Problem Statement: Min Steps to one
Problem Level: EASY
Problem Description:
Given a positive integer 'n', find and return the minimum number of steps that 'n' has to take to get reduced to 1. You can perform any one of the following 3 steps:
1.) Subtract 1 from it. (n = n - ­1) ,
2.) If its divisible by 2, divide by 2.( if n % 2 == 0, then n = n / 2 ) ,
3.) If its divisible by 3, divide by 3. (if n % 3 == 0, then n = n / 3 ).

Write brute-force recursive solution for this.
Input format :
The first and the only line of input contains an integer value, 'n'.

Output format :
Print the minimum number of steps.

Constraints :
1 <= n <= 200

Time Limit: 1 sec

Sample Input 1 :
4

Sample Output 1 :
2

Explanation of Sample Output 1 :
For n = 4
Step 1 : n = 4 / 2 = 2
Step 2 : n = 2 / 2 = 1

Sample Input 2 :
7

Sample Output 2 :
3

Explanation of Sample Output 2 :
For n = 7
Step 1 : n = 7 ­- 1 = 6
Step 2 : n = 6 / 3 = 2
Step 3 : n = 2 / 2 = 1

Create a class named Shape with a function that prints "This is a shape". Create another class named Polygon inheriting the Shape class with the same function that prints "Polygon is a shape". Create two other classes named Rectangle and Triangle having the same function which prints "Rectangle is a polygon" and "Triangle is a polygon" respectively. Again, make another class named Square having the same function which prints "Square is a rectangle". Now, try calling the function by the object of each of these classes
