Introduction to DSA in Python 🧩
What is DSA?
Data Structures and Algorithms (DSA) is the foundation of efficient programming. **Data Structures** organize data, while **Algorithms** process it.
📚 Why Learn DSA?
⚡ Efficiency
Write code that runs faster and uses less memory.
🧠 Problem Solving
Develop a structured approach to solving complex problems.
🐍 Python for DSA
Python is an excellent language for DSA because of its readable syntax and powerful built-in data structures like Lists, Sets, and Dictionaries.
python
# Python makes DSA readable
# Swapping two numbers
a, b = 5, 10
a, b = b, a # No temp variable needed!
print(a, b) # 10 5💡 Did You Know?
Many top tech companies (FAANG) focus heavily on DSA during interviews to assess a candidate's problem-solving skills.
