What is Competitive Programming | Beginners Guide

How to start Competitive Programming? As the name suggests, it’s a competition of coding where you have to solve a question using your logic based on maths, algorithm, and data structure. You break the problem into small chunks and come up with a solution after analyzing the problem from different angles to minimize the time and space complexity.

The Ultimate SQL Guide for Beginners in 2020.

SQL is a standard language for storing, manipulating, and retrieving data in databases. In this article, I’ll teach you the very basic fundamentals of the SQL language and hope you will be able to write your own database queries at the end.

What does SQL Mean?

SQL stands for Structured Query Language and lets you access and manipulate databases.

Syntax

Most of the actions you need to perform on a database are done with SQL statements. The following SQL statement selects all the records in the “Users” table:

SELECT * FROM Users;

Select

The select statement is used to retrieve data from a database. The requested data is returned in a results table.

SELECT column1 FROM table_name;

Select Distinct

The Select Distinct statement is used to return only distinct (different) values.

SELECT DISTINCT * FROM table_name;

Count

The following SQL statement lists the number of different customer countries:

SELECT COUNT(DISTINCT Country) FROM Customers;

Where

The Where clause is used to filter records.

SELECT column1
FROM table_name
WHERE condition;

For example:

SELECT * FROM Users
WHERE Country='Netherlands';

AND, OR and NOT Operators

The Where clause can be combined with AND, OR, and NOT operators. The AND and OR operators are used to filter records based on more than one condition:

  • The AND operator displays a record if all the conditions separated by AND are TRUE.
  • The OR operator displays a record if any of the conditions separated by OR is TRUE.

The NOT operator displays a record if the condition(s) is NOT TRUE.

AND

SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 AND condition3 ...;

OR

SELECT column1, column2, ...
FROM table_name
WHERE condition1 OR condition2 OR condition3 ...;

NOT

SELECT column1, column2, ...
FROM table_name
WHERE NOT condition;

The Ultimate Java Guide for Beginners in 2020.

Java is a high-level programming language. It was initially designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. The Java syntax is similar to C++ but is strictly an object-oriented programming language.

I hope with this article that you’ll learn and understand the fundamentals of Java.

Getting Started

The first thing you need to do is install Java, and you can install an IDE such as Eclipse or IntelliJ.
