Daily Coding Practice 🧠

Welcome to my daily coding practice repo!

Here, I solve basic to advanced coding problems from various sources like PrepInsta, LeetCode, GeeksforGeeks, etc.

I solve interesting problems regularly to improve my skills in:

  • Problem Solving
  • Data Structures and Algorithms (DSA)
  • Coding for Interviews
  • Logical Thinking

Structure

  • Each Day-X folder contains 1 or more problems solved on that day.
  • Files are named as Q1, Q2, ... based on the number of questions solved.

📚 What you will find here

  • ✅ Daily coding questions
  • ✅ PrepInsta / LeetCode / GFG / Practice sets
  • ✅ Clean and optimized Python solutions
  • ✅ Simple code explanations

My Goal

To build consistency and strong problem-solving skills! 🚀. "Consistency is the key to mastery. Solving problems daily to strengthen my DSA skills and get better every day."
