Mastering Data Structures & Algorithms using C, Java, C++ ·
Data Structure way of organizing data in a computer .
Example: Arrays, Stack, Queue,List , Graph etc

Below is some point to be consider before implementing :-
What kind of information will be stored with help of data structure? Where should data persist, or be kept, after it is created ? What is the best way to organize the data in multiple way? What aspects of memory and storage Optimization ?

I will add the most important point that before learning data structure and algorithms, you must be familiar with programming languages like C++, C, Python, etc

Below is an example of   Demonstration of Array   ..

 #include <stdio.h>
 int main() {       
              //array declaration   
                int rollNo[10];
               //taking inputs
                for(int i=0;i<10;i++)
                for(int i=0;i<10;i++)
                printf("%d ",rollNo[i]);
                 return 0;
 Input:          12 13 34 56 12 87 56 78 23 10 
 Output:         12 13 34 56 12 87 56 78 23 10 

Start with some of the most common data structures with definition

  1. Arrays
    Array used to store a collection of elements of the same type in a contiguous block of memory and each identified by an index or a key.
  2. Linked Lists
    A linked list is a type of linear data structure made up of nodes that all point to one another.
  3. Stacks
    The last element inserted is the first one withdrawn in a stack, which is an example of a last-in-first-out (LIFO) data structure.
  4. Queues
    The first element added is the first one withdrawn in a queue, which is a first-in-first-out (FIFO) data structure.
  5. Trees
    A tree is a type of hierarchical data structure made up of nodes and edges.
  6. Graphs
    A graph is made up of nodes (also known as vertices) and the edges that connect them.
  7. Hash Tables
    A data structure known as a hash table stores key-value pairs and enables quick access to items based on their keys.

Mandatory Tools you will need to install

  • you will need a Pentium 200-MHz computer with a minimum of 128 MB of RAM
  • Linux 7.1 or Windows 95/98/2000/XP operating system.
  • C compiler and C++ compiler
  • we write code in compiler to execute all the concepts as a program

Books: Books are the best source of information.

Data structures, which are fundamental ideas in computer science, are used to arrange and store data in a way that makes it possible for operations and retrieval to be performed quickly. They serve as the foundation for numerous algorithms and applications. Here we saw few of the most popular data structures and their fundamental operations.
