💻 Coding Interview Foundations — Part 1: Programming Language 🚀

Before jumping into Data Structures & Algorithms, master one programming language deeply. (Recommended: Python — simple, powerful, interview-friendly ⭐)

🔹 What You Must Master
✅ 1. Syntax & Basics
- Variables
- Data types → int, float, str, bool
- Lists, Tuples, Sets, Dictionaries
- Input / Output
- Type casting
👉 If syntax is weak → logic won’t help in interviews.

✅ 2. Loops & Conditions
- if-else statements
- for loop
- while loop
- break, continue
- Nested loops
🔥 Used in almost every coding problem.

✅ 3. Functions
- Function definition
- Parameters & return values
- Default arguments
- Recursion basics
✔ Helps write modular and structured code.

✅ 4. Important Built-in Libraries (Python Users ⭐)
- collections → Counter, defaultdict
- heapq → Priority Queue
- math
- itertools
Using built-ins efficiently = strong problem solving.

✅ 5. Writing Clean Code
- Meaningful variable names
- Small reusable functions
- Handle edge cases
- Clear logic structure
Interviewers evaluate thinking + code quality.

⏱️ Recommended Time
Beginner → 2 weeks
Intermediate → 4–5 days revision
Daily: 30 min concept revision
1–2 practice problems

❌ Avoid These Mistakes
- Learning multiple languages at once
- Jumping to advanced topics too early
- Memorizing solutions without understanding
