A tuple in Python is an immutable collection of elements, similar to a list but cannot be changed once created.
Tuples are created using parentheses ()
Elements in a tuple can be of different data types
Tuples can be accessed using indexing or slicing
Tuples are faster than lists as they are immutable
A dictionary in Python is a collection of key-value pairs, where each key is unique and maps to a corresponding value.
In Python, dictionaries are created using curly braces {} and key-value pairs separated by colons.
Keys in a dictionary must be immutable objects, such as strings, numbers, or tuples.
Values in a dictionary can be of any data type, including lists, tuples, or even other dictionaries.
The 'in' keyword in Python is used to check if a value exists in a sequence (list, tuple, string, etc.)
Used to check if a value is present in a sequence
Returns True if value is found, False otherwise
Can be used with lists, tuples, strings, dictionaries, etc.
Sorting in Python refers to arranging elements in a list in a specific order.
Sorting can be done using built-in functions like sorted() or sort()
Elements can be sorted in ascending or descending order
Sorting can be done based on custom key functions

The 4 pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation restricts access to certain components of an object, protecting its integrity.
Abstraction hides complex implementation details and only shows the necessary features.
Polymorphism allows objects of different classes to be treated as objects of a
HashMap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
Retrieving a value involves hashing the ...

The question is asking for the current time and the angles formed by the hour and minute hands on a clock.
The angle between the hour and minute hands of a clock can be calculated using the formula: angle = |(30*hour - (11/2)*minutes)|
At 3:00, the angle between the hour and minute hands is 90 degrees.
At 6:00, the angle between the hour and minute hands is 180 degrees.
At 9:00, the angle between the hour and minute hands
