In the world of software development, data structures play a crucial role in organizing and manipulating data efficiently. Understanding the fundamentals of data structures is essential for every programmer.

Data structures are objects that allow us to store, organize, and access data in different ways. They provide a way to represent the relationships between data elements and determine how data can be stored, retrieved, and modified.

As a senior engineer with experience in Java, Spring Boot, and MySQL, you have likely encountered various data structures in your coding journey. These include arrays, linked lists, stacks, queues, trees, and more.

In this lesson, we will explore the different types of data structures, their properties, and their applications. We will dive deep into each data structure, discussing their operations, time complexity, and space complexity.

Let's start our journey into the fascinating world of data structures and algorithms, where we will learn how to efficiently solve complex problems using the right data structures and algorithms.

1// Let's start with a simple example: printing 'Fizz' for multiples of 3, 'Buzz' for multiples of 5, and 'FizzBuzz' for multiples of both 3 and 5.

3class Main {
4  public static void main(String[] args) {
5    for(int i = 1; i <= 100; i++) {
6      if(i % 3 == 0 && i % 5 == 0) {
7          System.out.println("FizzBuzz");
8      } else if(i % 3 == 0) {
9          System.out.println("Fizz");
10      } else if(i % 5 == 0) {
11          System.out.println("Buzz");
12      } else {
13          System.out.println(i);
14      }
15    }
16  }
