AVASOFT Interview Questions and Answers for Freshers

A string reverse program takes an input string and returns it in reverse order, demonstrating basic string manipulation.

• Use built-in functions: Many languages have built-in functions to reverse strings. Example in Python: `reversed_string = input_string[::-1]`.

• Iterative approach: Loop through the string from the end to the beginning. Example in Java: `for (int i = str.length() - 1; i >= 0; i--) { ... }`.

• Recursive approach: Define a function that calls itself with a smaller su...read more

YouTube generates revenue primarily through advertising, subscriptions, and partnerships.

• Advertising: YouTube displays ads before, during, or after videos. For example, TrueView ads allow users to skip after 5 seconds.

• YouTube Premium: Subscribers pay a monthly fee for ad-free viewing, access to exclusive content, and offline downloads.

• Channel Memberships: Creators can offer memberships for a monthly fee, providing perks like exclusive content and badges.

Regression testing ensures changes don't break existing functionality. Smoke testing checks basic functionality. Unit testing tests individual units of code.

• Regression testing: retesting of previously tested functionality to ensure changes haven't introduced new defects

• Smoke testing: quick check to ensure basic functionality is working before more comprehensive testing

• Unit testing: testing individual units of code to ensure they function as expected

• Example: Regression testing...read more

A tuple is an ordered collection of elements. OOPs stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.

• Tuple is a data structure that can store multiple elements of different data types.

• In OOPs, data and behavior are encapsulated within objects.

• Examples of OOPs languages include Java, C++, and Python.

Dynamically typed languages do not require variable types to be declared explicitly.

• Variables do not have a fixed data type

• Data types are determined at runtime

• Examples include Python, JavaScript, and Ruby

OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPs focuses on creating objects that interact with each other to solve a problem.

• Encapsulation: Bundling data and methods that operate on the data into a single unit (object).

• Inheritance: Allows a class (subclass) to inherit properties and behavior from another class (superclass).

• Polymorphism: Ability to present the same interface for different data t...read more

Program to sort a list without using built-in functions

• Iterate through the list and compare each element with the rest to find the smallest element

• Swap the smallest element with the first element in the list

• Repeat the process for the remaining elements until the list is sorted
