Find the largest prime number in array using Segmented Sieve.

• Implement Segmented Sieve algorithm to generate prime numbers up to the maximum value in the array.

• Iterate through the array and check if each number is prime using the generated prime numbers.

• Return the largest prime number found in the array.

OOPs stands for Object-Oriented Programming and it is a programming paradigm based on the concept of objects.

• OOPs is based on four main concepts: Encapsulation, Inheritance, Polymorphism, and Abstraction.

• Encapsulation is the process of hiding the implementation details of an object from the outside world.

• Inheritance allows a class to inherit properties and methods from another class.

• Polymorphism allows objects of different classes to be treated as if they were of the same cla...read more

Program to print a given pattern using an array of strings.

• Create an array of strings to hold the pattern

• Use nested loops to iterate through the array and print the pattern

• Adjust the loops to print the desired pattern

• Example: for a right triangle pattern, use i for rows and j for columns, and print '*' if j<=i

The process is called coding and it involves assigning a unique code to something for identification or classification.

• Coding is used in various fields such as software development, medical coding, and data analysis.

• The codes assigned can be alphanumeric or numeric depending on the system used.

• Examples of coding systems include ASCII, Unicode, ICD-10, and CPT codes.

• Coding helps in organizing and managing large amounts of data efficiently.

• Bachelor's degree in Computer Science

• 5 years of experience as a Software Developer

Reverse a string without using pre-defined functions.

• Iterate through the string from the last character to the first.

• Create a new string and append each character to it in reverse order.

Overloading is having multiple methods in the same class with the same name but different parameters. Overriding is implementing a method in a subclass that is already defined in the parent class.

• Overloading allows a class to have multiple methods with the same name but different parameters.

• Overriding involves implementing a method in a subclass that is already defined in the parent class.

• Overloading is resolved at compile time while overriding is resolved at runtime.

• Example ...read more

A Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

• Start with two initial numbers, usually 0 and 1.

• Add the two preceding numbers to get the next number in the series.

• Repeat this process to generate the Fibonacci series.

• Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, ...

Abstraction is the concept of hiding complex implementation details and showing only the necessary features of an object.

• Abstraction allows us to focus on what an object does rather than how it does it

• It helps in reducing complexity and improving efficiency

• Examples of abstraction include interfaces in Java, where only method signatures are defined without implementation details

Inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class.

• Allows a class to inherit attributes and methods from another class

• Promotes code reusability and reduces redundancy

• Creates a parent-child relationship between classes

• Derived class can override methods from the base class

• Example: Class Car can inherit from class Vehicle
