My DSA §

Welcome to the Data Structures and Algorithms (DSA) repository. This document provides an overview of key data structures and examples implemented in Java.

Key Concepts §

Data Structures and Algorithms are crucial for:

• Efficient Data Storage and Retrieval
• Optimizing Performance
• Effective Problem Solving

Data Structures §

Here is a list of common data structures:

1. Array

   -Largest in array

   -Second Largest in Array

   -Check if Array is Sorted

   -Remove Duplicates from Array

2. Linked List

3. Stack

4. Queue

5. Hash Table

6. Tree

   • Binary Tree
   • Binary Search Tree (BST)

7. Heap

8. Graph

Java Examples §

Array §

// Array
int[] array = {1, 2, 3, 4, 5};

Linked List Node §

// Linked List Node
class Node {
    int value;
    Node next;
    
    Node(int value) {
        this.value = value;
        this.next = null;
    }
}

Stack §

import java.util.Stack;
 
// Stack
Stack<Integer> stack = new Stack<>();

Queue §

import java.util.LinkedList;
import java.util.Queue;
 
// Queue
Queue<Integer> queue = new LinkedList<>();
