Скачать или смотреть Binary Search algorithm Explained Step By Step |Data structures and algorithms for beginners part 4

In this video, we break down the Binary Search Algorithm from absolute zero to real-world implementation.
If Binary Search feels confusing, slow, or “too theoretical,” this video fixes that permanently.

We start with why algorithms exist, move into why search algorithms are needed, and then clearly explain why Binary Search is faster than Linear Search using real-life examples like grocery shopping, mobile contact search, and number systems.

This video is designed for:
Beginners in Data Structures and Algorithms (DSA)
Anyone who wants to truly understand time complexity, log n, and Big O notation
Learners who want to think logically before writing code
Everything is explained step-by-step, visually, and logically no memorization, only understanding.

✔️ What is Binary Search Algorithm (from basics)
✔️ Why we need search algorithms in programming
✔️ Difference between Linear Search vs Binary Search
✔️ Why Binary Search works only on sorted arrays
✔️ Understanding log n with clear numerical examples
✔️ Time Complexity explained using Big O (O(log n))
✔️ Real-world example: Mobile phone contact search
✔️ How Binary Search works in real-time systems
✔️ Writing clean pseudocode before coding
✔️ Solving Binary Search with 2 full practice examples
