#Problem Solving

This repository contains solutions to various Data Structures and Algorithms (DSA) problems from platforms like LeetCode, GeeksforGeeks, InterviewBit, etc. The solutions are primarily written in Java and Python.

Project Overview

The aim of this repository is to provide a comprehensive collection of solutions to DSA problems, serving as a resource for anyone looking to learn or improve their problem-solving skills.

Repository Structure

The solutions are organized into folders based on the type of data structure or algorithm used:

BST: Problems related to Binary Search Trees.
Graph: Problems involving graph theory.
Bit Manipulation: Problems that require bit-level manipulation.
Priority Queue: Problems that involve the use of priority queues.
Recursion: Problems solved using recursive techniques.
Sliding Window: Problems solved using the sliding window technique.

Technologies Used

Java
Python
