Binary Search- First Occurrence & Last Occurrence -Introduction

🔍 The First & Last Occurrence problem uses Binary Search to efficiently find the starting and ending position of a target element in a sorted array. ⚡ Instead of stopping at the first match, we continue searching on the left or right side to find the exact boundaries. 📈 This approach works in **O(log n)** time complexity, making it much faster than linear traversal. 🎯 It is a very common interview problem and helps build strong Binary Search concepts. 🚀 This pattern is widely used in searching ranges, frequency counting, and duplicate element problems. #BinarySearch #DSA #Algorithms #CodingInterview #JavaProgramming #ProblemSolving #DataStructures #CompetitiveProgramming #LearnCoding #TechEducation
