Virtusa Interview Questions

Virtusa Technical Interview Questions 

1. What are the different types of sorting algorithms?

Insertion sort and bubble sort are both sorting algorithms used in programming. Insertion sort works by comparing each element in an array to the elements before it, and inserting it into the correct position in the sorted subarray. Bubble sort works by repeatedly swapping adjacent elements if they are in the wrong order until the entire array is sorted.

2. Explain Object oriented programming?

Object oriented programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behaviour. 

3. Difference between linked list and queue.

A linked list and a queue are both data structures. Each node in a linked list has a value and a reference to the following node in the sequence. A linked list is a linear data structure whose items are kept in discrete objects called nodes. A data type called a queue adheres to the First-In-First-Out (FIFO) rule. Enqueue (putting an element to the rear) and dequeue (removing an element from the front) are its two main operations, which represent a collection of items.

4. What is ‘classpath’ environment variable? 

In Java and certain other programming languages, the 'classpath' environment variable is used to define the location of classes and other resources needed by the programme.

5. Explain operator overloading and overriding.

Operator overloading is the capacity to modify an operator's behaviour for a certain type. It enables the usage of operators like +, -, *, /, etc. with operands of custom classes. Contrarily, the ability to redefine an inherited operator's functionality in a subclass is known as operator overriding. A class that derives from another class has the ability to override how some operators behave that were passed down from the superclass.

6. What are the major data types in MySQL?

• INTEGER: Used to store whole numbers, both positive and negative, within a specified range.
• FLOAT and DOUBLE: Used to store floating-point numbers with decimal precision. 
• DECIMAL: Used to store fixed-point decimal numbers with precise decimal precision. It is commonly used for financial and monetary calculations.
• CHAR and VARCHAR: Used to store strings of characters. CHAR stores fixed-length strings, while VARCHAR stores variable-length strings, optimizing storage space.
• DATE, TIME, DATETIME, and TIMESTAMP: Used to store date and time values. DATE stores dates in the format 'YYYY-MM-DD', TIME stores time values, DATETIME stores both date and time, and TIMESTAMP stores a timestamp representing a specific time.
• BOOLEAN: Used to store boolean values, representing true or false.
• BLOB and TEXT: Used to store binary large objects (BLOB) and text data (TEXT), such as images, documents, or large text blocks.

7. What are MySQL views?

In MySQL, a view is a virtual table derived from the result of a query. It does not store any data physically but provides an alternative way to represent the data stored in one or more tables. A view is created based on a SELECT statement and acts as a predefined query that can be referenced and used like a table.

8. What do you mean database?

The Document Object Model (DOM) is a programming interface for HTML and XML documents. It represents the document as a tree-like structure of nodes, where each node corresponds to an element, attribute, or text in the document.

Using the DOM, developers can manipulate the content and structure of an HTML document dynamically. They can add or remove elements, modify attributes and text, and respond to user events.

15. How you can optimize code in CSS?

16. Explain closure functions in JavaScript.

In JavaScript, a closure is a combination of a function and its lexical environment (the scope) within which the function was declared. It allows a function to access variables from its outer scope even after the outer function has finished executing.

17. What is the difference between == and === ?

The == operator performs type coercion, which means it converts the operands to a common type before comparison and on the other hand, the === operator performs strict equality comparison. It compares the values of the operands without performing type coercion. It checks for both value and type equality.

18. Difference between element and tag?

White spaces are a blank sequence of space characters, which is treated as a single space character in HTML. Because the browser collapses multiple spaces into a single space, you can indent lines of text without worrying about multiple spaces.

23. Explain the key difference between local storage and session storage objects.
