If, in a recursive solution, function A calls function B which calls function C, this is called<u> Indirect</u> recursion.
A recursive algorithm is said to be recursive if such an algorithm calls itself with smaller input values and get current result for implementing basic operations on those simple inputs.
Indirect recursion occurs when a function A invokes another function B which in turn makes it the original function and calls another function C.

Answer:
Polymorphism
Explanation:
You can have a basic button class that gets inherited by other classes.
class Button {
function pushButton(){}
}
class ElevatorButton extends Button{};
class BigRedButton extends Button{};
With these new classes, they inherit from the basic button class. They can decide what happens when the method pushButton() is called.
You don't need to worry about what pushButton() actually does, you can just call it if the object is of the type "Button" and you can expect it to work.
Answer:
Windows has GUI, where its predecessor DOS does not.
Explanation:
DOS required the user to type instructions into the computer through an interface system known as command line.
Windows has graphical user Interface (GUI), that allows commands in a more user friendly environment than DOS.
Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
