*🔍 Master Binary Search in Minutes! | Binary Search Algorithm Explained*
Looking to *understand Binary Search* once and for all? In this video, we break down **how Binary Search works**, when to use it, and the **three key phases**:
✅ *Pre-processing* – Sorting the collection (if needed)
✅ *Binary Search Execution* – Dividing the search space in half
✅ *Post-processing* – Handling edge cases like first/last occurrences
We also discuss *common variations* and answer key questions:
❓ Why are there different implementations?
❓ How do you choose the right approach?
❓ What are the best templates to follow?
🔥 *By the end of this video, you’ll confidently apply Binary Search in coding interviews and real-world problems!*
💡 *Practice Problems:*
Find an element in a sorted array
First & last occurrence of a number
Search in a rotated sorted array
