Lists and tuples are both data structures in Python, but lists are mutable while tuples are immutable.

• Lists are denoted by square brackets [] while tuples are denoted by parentheses ().

• Lists can be modified after creation, while tuples cannot be modified.

• Lists are used for collections of items that may need to be changed, while tuples are used for fixed collections of items.

• Example: list = [1, 2, 3] ; tuple = (4, 5, 6)

Merge sort and Heap sort are both comparison-based sorting algorithms, but they differ in their approach and performance.

• Merge sort is a divide-and-conquer algorithm that divides the input array into two halves, recursively sorts them, and then merges the sorted halves.

• Heap sort is based on the concept of a binary heap, which is a complete binary tree where each node is greater than or equal to its children. It involves building a max heap and repeatedly extracting the maximu...read more

CSS can be used in web pages through inline, internal, and external methods.

• Inline CSS is used within the HTML tag using the style attribute.

• Internal CSS is used within the head section of the HTML document using the style tag.

• External CSS is used in a separate file and linked to the HTML document using the link tag.

• CSS preprocessors like Sass and Less can also be used to write CSS in a more efficient way.

• CSS frameworks like Bootstrap and Foundation provide pre-written CSS co...read more

Stacks and queues are data structures used to store and retrieve elements in a specific order.

• Stacks follow the Last-In-First-Out (LIFO) principle, where the last element added is the first one to be removed.

• Queues follow the First-In-First-Out (FIFO) principle, where the first element added is the first one to be removed.

• Stacks can be implemented using arrays or linked lists.

• Queues can also be implemented using arrays or linked lists.

• Examples of stack usage include the undo ...read more

The interview questions cover topics like encapsulation, structures vs classes, arrays vs pointers, and project explanation.

• Encapsulation refers to bundling data and methods that operate on the data into a single unit. Example: a class in object-oriented programming.

• Structures are used to group different data types into a single unit, while classes can also include methods to operate on the data. Example: struct vs class in C++.

• Arrays are collections of elements of the same d...read more

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.

• Encapsulation helps in hiding the internal state of an object and only exposing the necessary functionalities.

• For example, a car can be seen as an encapsulated object where the internal details like engine, transmission, etc. are hidden and only the methods like start, stop, accelerate are accessible.

• Encapsulation also helps in achieving data abstraction and data hiding in ob...read more

Java is an object-oriented programming language while C is a procedural programming language.

• Java is platform-independent while C is platform-dependent.

• Java has automatic garbage collection while C requires manual memory management.

• Java has built-in support for multithreading while C requires external libraries.

• Java has a larger standard library compared to C.
