In this video, we solve an important Binary Search problem: **Find the First Occurrence of an Element in a Sorted Array**.
This is a very common variation of Binary Search asked in coding interviews and helps build intuition for many other Binary Search patterns.
📌 In this video we cover:
• Problem explanation
• Why normal Binary Search is not enough
• How to modify Binary Search to find the first occurrence
• Step-by-step dry run with an example
• Time Complexity and Space Complexity
Understanding this pattern will help you solve problems like:
• First and Last Occurrence in Sorted Array
• Count Occurrences of an Element
• Lower Bound / Upper Bound
• Search Range problems
Binary Search is one of the most important algorithms for **DSA and coding interview preparation**.
If you're preparing for coding interviews or learning Data Structures & Algorithms, this series will help you build strong fundamentals.
