π Welcome to Part 51 of Code & Debugβs 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.
π What youβll learn in this video:
β
Understanding the problem statement & constraints
β
Efficient Binary Search approach (O(log n)) for counting occurrences
β
Using First and Last Position Search to find count efficiently
β
Step-by-step Python implementation
β
Handling edge cases & edge scenarios
π‘ 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.
