Questions and Answers

What is the depth of recursion?

The number of times a function returns a value

The number of if-else statements in a recursive function

The number of recursive cases in a problem

The number of times a function calls itself (correct)

What does the base case refer to in a recursive function?

The initial input to the recursive function

The maximum number of recursive calls allowed

The condition when the function should call itself

The condition when the problem can be solved without recursion (correct)

Why are recursive algorithms usually less efficient than iterative ones?

Because they cannot handle repetitive problems

Because they do not involve base cases

Due to overhead of each function call (correct)

Because they have fewer if-else statements

Study Notes

Procedural Programming

Procedural programming involves writing programs made up of functions that perform specific tasks
Procedures operate on data items that are separate from the procedures themselves
Data items are commonly passed from one procedure to another
The focus of procedural programming is to create procedures that operate on the program's data

Object-Oriented Programming

Object-oriented programming is focused on creating objects
An object is an entity that contains data (known as data attributes) and procedures (known as methods)
Methods perform operations on the data attributes
Encapsulation is a key concept in object-oriented programming, where data and code are combined into a single object
