Aggregate functions in SQL are used to perform calculations on a set of values and return a single value.

• Common aggregate functions include SUM, AVG, COUNT, MAX, and MIN.

• SUM calculates the total of a set of values.

• AVG calculates the average of a set of values.

• COUNT counts the number of values in a set.

• MAX returns the highest value in a set.

• MIN returns the lowest value in a set.

Answering the question of writing name 100 times without using any loop.

OOPs stands for Object-Oriented Programming. Pillars of OOPs are Inheritance, Encapsulation, Abstraction, and Polymorphism. Lists and tuples are data structures in Python.

• OOPs stands for Object-Oriented Programming

• Pillars of OOPs are Inheritance, Encapsulation, Abstraction, and Polymorphism

• Lists and tuples are data structures in Python

• Lists are mutable while tuples are immutable

A recursion program is a function that calls itself until a base case is reached.

• Identify the base case and write the code to handle it

• Write the recursive case that calls the function with a modified input

• Ensure the recursive case moves towards the base case

• Example: Factorial function: function factorial(n) { if (n === 0) { return 1; } else { return n * factorial(n-1); } }

• Example: Fibonacci sequence: function fibonacci(n) { if (n <= 1) { return n; } else { return fibonacci(n-...read more

Remove duplicates from an array

• Use a loop to iterate through the array

• Use a hash table to keep track of unique values

SQL basics include querying databases, manipulating data, and managing database structures.

• SQL stands for Structured Query Language

• Used for querying databases to retrieve specific data

• Can also be used to insert, update, and delete data in databases

• Used for creating and modifying database structures like tables, indexes, and views

Java is a popular programming language known for its platform independence and object-oriented approach.

• Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM)

• It is object-oriented, allowing for the creation of reusable code through classes and objects

• Java uses a syntax similar to C++, making it easy for programmers to learn if they are familiar with C-based languages

The pillars of Python refer to the core principles that guide the design and development of the Python programming language.

• Readability counts: Python emphasizes code readability and simplicity, making it easier for developers to write and maintain code.

• Explicit is better than implicit: Python encourages clear and explicit code over ambiguity and complexity.

• Simple is better than complex: Python promotes simplicity and straightforward solutions to problems.

• There should be one-...read more
