FREE 12 Coding Interview Patterns That Actually Get Asked PDF 👉https://tinyurl.com/12-coding-patterns WHY YOU NEED THIS GUIDE: • *Instant Recognition**: Learn exactly when to use specific techniques, such as **Two Pointers* or **Sliding Windows**. • **Think Like an Interviewer**: Understand what is actually being tested. • *Mental Models for High Pressure**: When time is ticking, you don't need a script, you need a mental model. Whether it's the "Expand and Contract" of **Sliding Windows* or "Choose → Explore → Unchoose" of **Backtracking**, these frameworks give you a clear place to start. ----- Master the Square Root of Integer Problem (FAANG Interview Prep) Looking to ace your next coding interview at **Facebook, Amazon, or Microsoft**? In this video, we break down the classic "Square Root of Integer" problem. While it sounds simple, this "easy" difficulty problem has a surprisingly low success rate. We’ll show you exactly why and how to avoid common pitfalls—like handling integer overflows and meeting the strict O(log n) time complexity requirement. 🚀 What You’ll Learn: *Binary Search Optimization:* Why a simple linear loop is too slow and how to use binary search to converge on the floor of a square root. *Handling Edge Cases:* How to manage inputs like 0 and 1 efficiently. *Avoiding Overflows:* Why using `long` for intermediate calculations is critical when input reaches `INT_MAX`. *Step-by-Step Walkthrough:* Watch a dry run of the algorithm to see how it handles both perfect squares and non-perfect squares. --- *Don't forget to:* ✅ *Like* if this helped you. ✅ *Subscribe* for more FAANG-level problem walkthroughs. #CodingInterview #FAANG #BinarySearch #InterviewBit #Algorithms #DataStructures #softwareengineering ----- 0:00 Introduction to the Square Root Problem 1:24 Why the O(log A) constraint means we need Binary Search 3:47 Intermediate calculations: Using Long vs Int 5:44 Converging on the "Floor" of a square root 7:13 Dry run: Walking through an example 9:55 Final summary and interview tips
