LeetCode Solutions 🚀

This repository contains my solutions to various LeetCode problems, written in C++.
I am solving these problems daily as part of my Data Structures & Algorithms (DSA) practice.

📂 Structure

Each file is named as lc<problem_number>_<problem_title>.cpp
Example: lc121_best_time_to_buy_sell.cpp → Solution for LeetCode 121. Best Time to Buy and Sell Stock

🛠️ Topics Covered (and growing)

Arrays
Strings
Hashing
Two Pointers
Sorting
Dynamic Programming
Graphs
More coming soon...

✅ Progress

Problems solved: (update this number weekly)
Language: C++
Goal: Consistency + Mastering problem-solving

💡 Motivation

This repo is a part of my journey to:

Improve problem-solving skills
Build strong fundamentals in DSA
Prepare for coding interviews
