Repo. to track progress of my DSA learning journey

JiteshBhashwani/DSA

This is a repository to track the progress of my data structures and algorithms (DSA) learning journey. I am following various online courses, books and websites to learn and practice DSA concepts and problems.

The repository contains the following directories:

• datastructures: This directory contains implementations of various data structures such as arrays, linked lists, stacks, queues, trees, graphs, etc. in C++.
• algorithms: This directory contains implementations of various algorithms such as sorting, searching, dynamic programming, greedy, backtracking, etc. in C++.
• problems: This directory contains solutions to various DSA problems from different platforms such as LeetCode, HackerRank, CodeChef, etc. in C++.

Note: This repository is still in progress and I am currently adding more content as I am learning. Some content may be in Java instead of C++.

Motivation

I created this repository to document my learning process and to showcase my skills and knowledge in DSA. I believe that DSA is an essential topic for any software engineer or programmer who wants to solve complex problems efficiently and elegantly. I also enjoy learning new things and challenging myself with different types of problems.

Resources

The resources that I am using or have used for learning DSA are:

• Data Structures and Algorithms Made Easy by Narasimha Karumanchi
• Introduction to Algorithms by Thomas H. Cormen et al.
• GeeksforGeeks website
• Data Structures and Algorithms Through C In Depth by Abdul Bari
• Beginning C++ Programming - From Beginner to Beyond by Tim Buchalka's Learn Programming Academy, Dr. Frank Mitropoulos.
• YouTube channels:
  • Love Babbar DSA Playlist
  • Striver
  • CodeWithHarry
  • Kunal Kushwaha
  • Aditya Verma
  • Fireship

bug in push front

DSA/Data-Structures/LinkedListAdt/DoublyLinkedList/LinkedList.cpp

Lines 115 to 129 in bbff6e4

	void LinkedList::push_front(int x)
	{
	if(this->empty())
	{
	this->first = this->last = new node(x);
	}
	else
	{
	node* temp = new node(x);
	temp->next = this->first;
	this->first->previous = temp;
	this->first = temp;
	}
	}

pushing doesn't increase size of list
