🧠 Problem Solving by C++

Welcome to problem_solving_by_cpp 🚀

This repository is a collection of problem-solving solutions written in C++. Each file contains a clear solution to a specific problem, helping learners improve logic, coding skills, and familiarity with C++ tools including STL.

This repo is about practice, understanding, and growth — not just writing code.

---

🎯 Purpose of This Repository

• Build strong problem-solving skills using C++
• Practice algorithmic thinking and logic
• Apply C++ fundamentals and STL in real problems
• Prepare for exams, coding contests, and interviews
• Keep all practice code organized in one place

This repository is continually updated with new problems.

---

📚 Topics Covered

• C++ basics (loops, functions, conditions)
• STL usage (vector, map, set, stack, queue)
• Arrays and strings
• Searching techniques
• Sorting techniques
• Recursion problems
• Pattern printing
• Logical problem-solving

This repo focuses on clarity and understanding, not just code output.

🧠 Learning Philosophy

• Write readable, understandable code before optimization
• Learn C++ fundamentals while solving problems
• Practice consistently
• Learn from errors and debug actively

Problem-solving is skill built through repetition and understanding, not talent alone.

---

📌 Notes

• Solutions focus on clarity, not micro-optimization
• Complexity will increase gradually as you progress
• This is a learning repository, not a production-level library

---

🤝 Contribution

Contributions are welcome:

• Add new solved problems
• Improve readability and explanations
• Clean up logic for better clarity
