Lists are mutable in Python.
Lists can be modified after creation, allowing for addition, removal, and modification of elements.
Tuples, strings, integers, and floats are immutable in Python.
Example: list_example = [1, 2, 3]; list_example[1] = 5 # modifies the list element at index 1 to 5.
The code will print 'o wo', which is the substring of 'Hello world' starting from index 4 up to index 7.
The slicing operation str[4:8] extracts characters from index 4 to index 7 (exclusive) from the string 'Hello world'.
The index 4 corresponds to the character 'o' and index 7 corresponds to the character 'd'.
Therefore, the output of print(str[4:8]) will be 'o wo'.

Generator functions are functions that can be paused and resumed, allowing for lazy evaluation of data.
Generator functions use the yield keyword to pause execution and return a value.
They can be used to generate an infinite sequence of values.
They are memory efficient as they only generate values when needed.
Example: function* myGenerator() { yield 1; yield 2; yield 3; }
Example: const infiniteGenerator = function*() { ...
Push notifications can be implemented in Android and iOS using Firebase Cloud Messaging (FCM) and Apple Push Notification service (APNs) respectively.
For Android, integrate FCM SDK in the app and use FCM console to send notifications.
For iOS, create an APNs certificate, configure the app to receive notifications, and use APNs to send notifications.
Both platforms require handling of notification payload in the app to di...

Functional components are simpler and easier to test than non-functional components.
Non-functional components can have state and lifecycle methods, while functional components cannot.
Examples of functional components include buttons, labels, and icons, w...

Encapsulation ensures that the internal state of an object is hidden from the outside world
Inheritance allows a class to inherit...

To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
