TCS Intern Interview Questions and Answers

OOP stands for Object-Oriented Programming. It is a programming paradigm that uses objects and classes to organize code.

• OOP focuses on objects and classes, allowing for encapsulation, inheritance, and polymorphism.

• Objects are instances of classes that contain data and methods.

• In OOP, code is organized into reusable components, making it easier to maintain and scale.

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

Reverse a string and check if it's a palindrome.

• Create a function to reverse the input string.

• Compare the reversed string with the original string to check if it's a palindrome.

• Ignore spaces and punctuation when checking for palindrome.

• Example: Input 'racecar', reverse 'racecar' -> 'racecar', palindrome.

• Example: Input 'hello', reverse 'hello' -> 'olleh', not a palindrome.

Data structures are ways to store and organize data, while algorithms are step-by-step procedures for solving problems.

• Data structures are like containers that hold data in a specific layout, such as arrays, linked lists, trees, etc.

• Algorithms are the instructions or steps used to manipulate the data stored in data structures, like sorting or searching.

• Data structures focus on how data is stored and accessed, while algorithms focus on how to perform operations on the data eff...read more
