Can Counting Sort actually beat Quick Sort? 🤯
In this video, we’ll deeply understand the Counting Sort algorithm from scratch and learn why it can achieve linear time complexity O(n + k) under the right conditions.
You’ll learn:
✅ How Counting Sort works step-by-step
✅ Stable vs Unstable Counting Sort
✅ Support for negative numbers
✅ When you SHOULD use Counting Sort
✅ When you should NEVER use it
✅ Time Complexity of Counting sort
✅ Space Complexity of Counting sort
✅ Why complexity can be:
• Linear
• O(n + k)
• Quadratic/Exponential/Factorial
✅ Full JavaScript implementation
This episode is designed for:
• DSA learners
• Interview preparation
• Computer science students
• Software engineers wanting stronger fundamentals
