Welcome to the world of coding problems! In this lesson, we will be exploring various techniques and strategies for solving coding problems.

As a senior engineer with intermediate knowledge of Java and Python, you are already familiar with the fundamentals of programming. However, coding problems often require a different approach and level of thinking.

Whether you are preparing for coding interviews or simply looking to improve your problem-solving skills, this lesson will provide you with valuable insights and strategies.

Throughout this course, we will cover a wide range of topics, including arrays, strings, linked lists, trees, sorting and searching, dynamic programming, graphs, system design, object-oriented design, and behavioral interview questions.

To start things off, let's write a simple Java program to print "Hello, World!":

xxxxxxxxxx

public class Main {

    public static void main(String[] args) {

        System.out.println("Hello, World!");

    }

}
