🚀 Introduction
Competitive Programming (CP) is a skill where you solve algorithmic problems within a limited time. It helps you improve problem-solving ability, logical thinking, and coding speed.
If you are a complete beginner, don’t worry. This guide will help you start CP step by step.
🪜 Step 1: Learn a Programming Language
First, choose one language:
C++ (Highly recommended for CP)
OR Java / Python
👉 Focus on basics:
- Variables
- loops
- conditionals
- Functions
- Arrays & strings
🧠 Step 2: Learn Basic Data Structures
Start with:
- Array
- String
- Stack & Queue
- Basic STL (for C++ users)
🔍 Step 3: Solve Easy Problems First
Start from easy level problems:
- Codeforces (A problems)
- CodeChef (Beginner section)
- AtCoder Beginner Contest
👉 Don’t jump to hard problems early.
🔥 Step 4: Learn Important Topics Slowly
After basics:
- Sorting
- Binary Search
- Greedy
- Prefix Sum
- Recursion
- Basic DP (Dynamic Programming)
🏁 Step 5: Practice Daily
- Solve 1–3 problems daily
- Participate in contests
- Upsolve (very important!)
🧩 Step 6: Learn from Mistakes
If you can’t solve a problem:
- Read editorials
- Understand logic
- Try again yourself
💡 Final Tips
- Consistency is more important than speed
- Don’t compare yourself with others
- Focus on understanding, not memorizing
