Binary Search Algorithm Explained | Dry Run, Code & Prerequisites 🔍💻

Master the Binary Search Algorithm from scratch! In this video, we dive deep into the core concepts of Binary Search, explaining why sorting (Ascending or Descending order) is an absolute prerequisite before applying this powerful technique. 🔍💻

We walk you through a complete visual dry run and implementation using the standard lower and upper indices to calculate mid:

mid = ( lower + upper ) / 2

Stay tuned till the very end, as we drop a crucial hint about an optimized mid formula that prevents integer overflow, which we will uncover in the next video! 🧠🔥

What you’ll learn in this video:

Core Prerequisite: Why Binary Search only works on sorted data. 📊

Step-by-Step Dry Run: Visualizing the search space reduction. 📝

Mid Calculation: Understanding the standard formula and its workflow. ⏱️

Code Implementation: Writing clean, logical code with no doubts left! 💻
