10.3K views on YouTube

🚀 Welcome to Part 51 of Code & Debug’s DSA Python Course!

In this video, we solve “Count Occurrences of a Number in a Sorted Array” using Binary Search, a crucial problem frequently asked in coding interviews.

📚 What you’ll learn in this video:
✅ Understanding the problem statement & constraints
✅ Efficient Binary Search approach (O(log n)) for counting occurrences
✅ Using First and Last Position Search to find count efficiently
✅ Step-by-step Python implementation
✅ Handling edge cases & edge scenarios

💡 Why is this problem important?
Counting occurrences efficiently is a key concept in searching, frequency analysis, and competitive programming. This method avoids unnecessary linear searches and optimizes performance in sorted arrays.
