I appeared for an interview in Sep 2017.
A sorting algorithm is a method of arranging elements in a specific order.
Sorting algorithms can be categorized as comparison-based or non-comparison-based.
Common sorting algorithms include bubble sort, insertion sort, selection sort, merge sort, quicksort, and heapsort.
Efficiency of sorting algorithms is measured by their time complexity, space complexity, and stability.
Example: Sorting an array of strings in alphabet

I applied via Naukri.com and was interviewed in Jan 2022. There were 4 interview rounds.
Accessing id parameter in URL involves parsing the URL and extracting the id value.
Use the window.location object to access the URL of the current page.
Parse the URL using methods like split() or URLSearchParams to extract the id parameter.
Example: If the URL is 'http://example.com/page?id=123', you can access the id value by parsing the URL.

Copy constructor is a special type of constructor which creates a new object as a copy of an existing object.
Copy constructor is used to initialize a new object as a copy of an existing object.
It takes an object of the same class as a parameter.
It is called automatically when a new object is created from an existing object.
Example: class MyClass { public: MyClass(const MyClass& obj) { // copy constructor logic } };
Copy constructor is used to create a new object as a copy of an existing object, while assignment operator is used to assign values from one object to another.
Copy constructor is called when a new object is created from an existing object, while assignment operator is called when an existing object is assigned values from another object.
Copy constructor creates a new object with its own memory space, while assignment o...
A static function is a function that is associated with a class rather than an instance of the class.
Static functions can be called without creating an instance of the class.
Static functions are commonly used for utility functions that do not require access to instance-specific data.
Static functions are declared using the 'static' keyword in many programming languages.
Example: 'Math.max()' in JavaScript is a static fun
Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.
Start with 0 and 1 as the first two numbers in the series
Add the previous two numbers to get the next number in the series
Repeat this process to generate the Fibonacci series
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
Ensures a class has only one instance
Provides a global point of access to that instance
Commonly used in scenarios where only one instance of a class is needed, such as database connections or logging

Virtual inheritance allows a derived class to inherit from a base class without creating duplicate base class subobjects.
Virtual inheritance is used to resolve the Diamond Problem in C++ where a class inherits from two classes that have a common base class.
It ensures that only one copy of the base class is inherited by the derived class.
Virtual inheritance introduces a virtual base class subobject to the derived class,...
A class for string operations can include methods for concatenation, substring extraction, length calculation, etc.
Create a class with methods like concatenateStrings, extractSubstring, calculateLength, etc.

Association, aggregation, and composition are types of relationships between classes in object-oriented programming.
Association is a relationship where two classes are connected, but not dependent on each other.
Aggregation is a type of association where one class contains another class, but the contained class can exist independently.
Composition is a stronger form of aggregation where the contained class is part of the

O(n) refers to linear time and space complexity.
O(n) means that the time or space required by an algorithm grows linearly with the size of the input.
It implies that the algorithm's performance is directly proportional to the input size.
For example, if an algorithm takes 10 seconds to process 100 elements, it would take 20 seconds to process 200 elements.
O(n) complexity is considered efficient and desirable in most case
